Mazda CX-7 Check Engine Light

  • P2006 means that the IMRC valve isn't functioning properly. This is a problem with just about all CX-7's. The solution is for the dealer to take it apart elongate some holes and remount the part. I had this procedure done and my CEL came back on 2 weeks later for the same thing. I just had a new redesigned part put on yesterday. I think the part is on back order so Mazda is trying to fix the existing part until they can get a supply. My car also seems to drive better at low speed then it did before. Not as much lag or that rubber band effect when starting from a stop.
  • "you are not aware that that no jumper wire was required on Chrysler cars..."

    I didn't mention Chrysler in my statement. In my 1984 car you had to put a jumper in a plug under the dashboard. "Your results may vary." FWIW, I could get a monkey to plug in a scanner and pull my CX-7 codes, so to each his own.

    "I'm just suggesting that the industry level the playing field a bit so that less people get ripped off. I can live with the fact that: at this point in time if I really want to know what's going on with my car, I can buy a diagnostic tool and a shop manual."

    If you really can live with it, I'm not sure why we are even arguing. The playing field is just as level as it ever was, and I don't see the problem, unless we've gotten more lazy as a society. Via simple tools, online research, and Mazda publications, you and I can find out all we need to know about our cars, and there is no profit-driven conpiracy preventing that. Except maybe the fact that we are spending too much time posting back-and-forth.

    Also had my 3 month old CX-7 serviced yesterday. They replaced the gas cap with no questions due to recall. Also, there is a known issue with something called an IMRC valve, which actually requires them to elongnate the hole the valve goes into, creating more of an oval shape. Tech said they were automatically doing these two fixes for anyone coming in with CEL issue that was not explained by other codes.
  • Go check... I think your CEL has detected a major malfunction. :sick:

    Almost 3000 miles since my last CEL! Knock on wood, stay away from black cats, I won't walk under a ladder, and keep Republicans out of power! (oops, didn't want to bring politics into this forum) But hey, wanna keep anything that brings bad-luck away from me! :P

    It may not stop people from getting ripped off completly, but it will help. I don't understand why a few of you object to an idea that makes sense. Eliminate a light that tells you aboulutely nothing and replace it with a display that at least give you a clus as to what is wrong with your car. I don't have a problem spending the $60 and doing my own diagnostics, but many people might and my idea eliminates the need to do that for everyone. My idea has no negative impacts and would cost little to include into the vehicles. If you don't like my idea, that's OK too. It's no as if I can force anyone to see the forrest through the trees.

    No negative impacts? How about you ask a mechanic/technician if it has negative impact, or a service manager.

    They already HAVE problems with people like you who come and seem to think they know more about the car than the technicians do, demanding service bulletins be addressed (even if it doesn't apply to their specific car), yelling that their PCM needs to be flashed even though they have none of the issues the update is supposed to address, all because some guy on the web told them they NEEDED it. When people cruise the internet to educate themselves, that's good, but it's bad when that translates into them thinking they alway know more than the guys working on their car. It can (and does) lead to a lot of time wasted, backed up service schedules and unjustified warranty work (where no one gets paid). Walk in and start a conversation with any service manager like this - "I read on the internet..." and you'll immediately see by their reaction that what I'm telling you is true.

    Go out on the street and ask anyone if the error code on their car now reads a series of numbers will they take steps to look it up online to see what it means. Some will say "no" and some would PREFER the simple oil light, engine light, brake light method. P5492J means nothing... LESS to the average consumer than "brake light".

    And of the people who say "sure, give me the code" -- would they then do FURTHER research to figure out what an INSERT-OBSCURE-PART-HERE is, or would they know what's involved in replacing one? How many of them would know EXACTLY what gets done when they go for schedule maintenance? How long does it take to fix or replace X? How much should it cost? How many different ways can an issue be addressed - does a part need to be replaced or can something else be done? What happens when Internet Joe tells them "don't pay more than $100 for that!" and Internet Joe is barking up the very-wrong tree?

    Jeez, even your computer there throws relatively vague errors at you and you have to KNOW how to find out where to get more information on the exact nature of the error. Not every computer has those tools installed or readily at hand. That why places like Best Buy have a busy Geek Squad.

    For the technology and mechanically advanced, like you, go spend the $60 and get the code reader. And if you're griping about the price you haven't thought this issue out at all.

    And based on looking at car forums and seeing how their traffic PALES in comparison to the traffic on the road, it's OBVIOUS that there aren't a lot of people like you.

  • I think I'm mostly in agreement with you, but when you say "Walk in and start a conversation with any service manager like this - "I read on the internet..." and you'll immediately see by their reaction that what I'm telling you is true...." You will also find a fair amount of consumers who educated their dealers about service bulletins, etc. When the gas-cap issue first started coming out, many consumers knew about this valid problem before their service departments did. That's the great thing about these forums... I can tell you that the iPod interface is clunky before a lot of dealers even know they can order it, or what trim levels it works with.

    As far as the codes, the ones plaguing the CX-7 are really pretty limited so far, and several of us have said what the codes mean, according to www.OBDii.com, etc. The people who don't want to take the time to look them up do so by their own choice. But, every person is free to choose their own level of technical involvement with their car... :) I just don't like complaining about there "being secrets," because there aren't any secrets if you choose not to allow them.

    Hey Carlitos (little charlie ;))

    I agree with you as well as I know that *I* have educated my dealer on some things, but it's all in the approach... and I'm betting you know what I mean. I actually don't start with "I read on the internet..." LOL. I'm more knowledgeable than the average person on cars and it usually starts off with me asking more questions than the typical Joe, and it's all very friendly and then leads to "hey, I did hear about..." or "a mechanic I talked to thought..." -- you get the idea.

    There ARE too many people, and I see them here and other forums, instructing each other to demand TSBs be addressed (even if that driver wasn't having the problem) or PCM updates be performed. Unless anyone has educated themselves about their OWN car and how PCM updates and TSBs apply to their situation and their VIN number they shouldn't be DEMANDING anything. Ask questions, be pleasant and go in really educated... not just with some snippet off the internet.

    Since my last reply I asked at least four of my friends if they would prefer codes or "dummy lights" (which I didn't phrase that way - one of THEM did) and ALL prefered dummy lights. I'm guessing people who even know enough to realize that the computer in a car tosses an alphanumeric-valued code out to help diagnose an issue would ALSO know enough that they can get a code reader if they really want to, or just ASK the technician at the dealership to explain what the code was and what work was done.

    I don't think there's a grand conspiracy with car computers any more than there is with home computers and their vague error indicators. Anyone who wishes to seek, can find. It's just the probably 40% don't wish to seek, another 40% become dangerous individuals when they do seek, and the remaining 20% are fairly educated and reasonable in their dealings with the dealership.

    My percentages might be off, but I'm giving the reasonable, educated people a higher number than they probably deserve. ;) -- Like I said previous, I think those of us here fall into a very extreme minority compared to the majority of drivers who NEVER seek out info about their cars online (other than price and options when buying).
  • You make a lot of unsubstantiated assumptions and foster a lot of hostility towards people who's opinion differ from yours. Also your response simply has no credibilty since you obviously don't care about what repairs cost or how often you get ripped off. The mere fact that your are willing to toss your expensive Tech package out the window and exchange it by spending thousands more simply because it doesn't have a mute button and can't connect your IPOD borders on the insane unless you have money to burn. Obviously that's your choice, but don't pass judgement on the rest of the world that doesn't want to throw their money away. How can enter any discussion like this and attempt to enlighten us when you didn't even have the forethought to try out the radio and discover it didn't have a mute button? Must have been all that Zoom Zoom excitement that overloaded you sensory input. It's just not fair that you pass judgement on others when you obviously have more money than the rest of us or just plain don't care how you spend it. People like you could care less as they walk out of the dealer paying for repairs they don't need. They must love it when you walk in to the dealership.

    I just hope you don't cause accidents playing with your IPOD searching for your favorite punk rock. I for one will stay clear of any white CX7s with tinted windows just in case it's you driving the "SUV they never saw coming".

    Have a nice day, unless you make other plans! :)

    Some of these tirades are becoming a little too personal. Let's stick to issues and suspend the personal judgments.

    tidester, host
  • cxrabbitcxrabbit Posts: 134
    My tech package included things other than the radio... and I've said myself I realize it's excessive but a good audio experience is important to me. And if I decide to rip out the radio it's my mistake to pay for.

    My opinion regarding car repairs shares little relevance with my decision on the radio. I DON'T get ripped off going for repairs or pay for things I don't need, and already told you I know more about cars than the average person. I have a good experience at all the dealerships and auto-shops I've been to. I'm a pleasant but educated person, and have respect for technicians and what they do. I grew up around parts guys, mechanics and cars.

    And since our host has reminded us to play nice I won't say what I'd really like to you. I bet YOU didn't test your radio for mute and pause because they are such BASIC features most people wouldn't. You assume they're included. I bet YOU didn't test how the random feature works either. Did you bring MP3 CDs with you, because I did. Did you ask Mazda about whether they'd support the iPod in the future. Do you know how many interface cables are available? Do you know how they work? I do. What companies make them? Any idea? I could give you a list.

    The only person passing judgement is you. My reply was clear to answer your points, and the fact that the information you so adamently want is available to you for a simple $60 solution. Most people DON'T want it and don't spend time on the internet in car-geek forums like you and I.

    And obviously my post contained something that range true to piss you off enough to come out attacking.
  • Here's the lastest on my third CEL. I've already had the gas cap replaced and the IMRC modification. Turns out the modification had to be...modified. So, the dealer removed the switch and elongated the holes to the new specifications. They also removed the actuator and expanded socket and gave the whole thing a lithium lube (you understand, I'm just quoting from the invoice--I have no idea what I just wrote). Hope this cures what ails my CX-7!
  • maltbmaltb Posts: 3,572
    Well I hope it works for your sake but it looks like many have found that only replacing the IMRC actuator is doing the trick. It looks like Mazda is just buying time to procure enough of those for the masses.
  • "...the fact that the information you so adamently want is available to you for a simple $60 solution. Most people DON'T want it and don't spend time on the internet in car-geek forums like you and I."

    The problem is that what I want has been misinterpreted several times by a few people. I never suggested that the dashboard display a code in lieu of going out and buying a diagnostic scanner. The technology to display error codes on the dash is old and vehicles have had the ability to display codes since the 80's if you knew how to retrieve them. I stated that the technolgy is there and that cars should display the actual error. In essence a smart idiot light that displys the actual error in english. The way things are now, the CEL comes on for things that are not an engine issue. That is my major objection to CEL light and they seem to keep tacking more things to it. As an example and as many of us here know, many cars today display a check engine light when someone forgets to tighten their gas cap. If the consumer is not aware of this, it generally means a trip to the dealer or repair shop for no reason. In warranty it doesn't sound so bad and many dealers might not charge for the diagnostic as a courtesy, but they can since it is a customer error. Out of warranty you could be charged whatever the basic 1 HR labor rate, assuming you are at reputable dealer and he is honest about what is causing the CEL condition. You are also subject to the inconvenice of bringing it in for service for and or taking time off from work or leaving the vehicle for the day. That is just one example of why we need something better. Basically we need better idiot lights since these days we have better idiots. If a gas cap is lose it should display a Check Gas Cap (CGC) light. That's just one example but there are others. So anyone who thinks my suggestion is a bad idea, shoot me, but I'm done with this topic.
  • cxrabbitcxrabbit Posts: 134
    LOL, I thought we had moved on from this now.

    Your idea is fine and all (though I stand by what I said earlier), but unfortunately the system can't detect a loose gas cap... what it detects, I believe, is loss in pressure. That REAL cause of the problem could be different things, one of which, yes, is a loose gas cap, but not always.

    So what should the car display then: All the possibilities? Like a CNN News Scroll? Maybe in the future when we all have computer screens in the car as standard that could be a feature to suggest. But right now, I think the gauge cluster is already a bit busy, don't you?

    ;)

    Back to the original topic...

    I dropped my car off at the dealer tonight for the CEL that popped on Wednesday night. Car will be there all day tomorrow. Service Manager was great and we both know it's NOT the gas cap so he's pretty sure the code will show it's the IMRC Valve (he says it's becoming a "common" issue). Hopefully will get all fixed tomorrow. Will keep you posted.
  • So if it gets diagnosed as the IMRC valve and it gets replaced, can we expect the CEL problem to go away forever?

    I've had the gas cap replaced (which apparently did nothing) and I am now driving around with the CEL on full time delaying a trip to the dealer as I don't want to go there 5 times to get the problem fixed......

    So are all these other "fixes" unnecessary? Or are there actually 4-5 legit causes of the CEL coming on? I would be amazed that a single car could be afflicted with 5 defects all resulting in the CEL lighting up. If this is really the case, those of us driving around in a CX-7 are in big trouble.........

    If I need to visit my dealer more than twice for the CEL, I will pursue legal action to walk away from the current lease.
  • That's the 3rd or 4th time you've said "I'm done with this topic." These forums sure are addictive, aren't they? :P

    The gas cap issue is a ringer of a situation. It would be tough for OBDII to know where a pressure loss in a sealed system actually is - therefore, there probably would never be a "Gas Cap Warning" possible under the current system. It just so happens that the gas cap is by far the weakest link in the system and most probable issue when a pressure loss is reported by OBDII.

    In a most other cases, the OBDII code is so specific (because it's technically possible with those components) that it's not misinterpretable.

    FWIW, I don't blame anyone for not wanting to know how to change their oil - but assuming the vehicle manufacturer had a decent design to start with, not knowing how to tighten a gas cap is really inexcusable.
  • astegmanastegman Posts: 171
    So if it gets diagnosed as the IMRC valve and it gets replaced, can we expect the CEL problem to go away forever?

    For me, no. I had the IMRC valve re-positioned (it was getting stuck, so they took it off and re-attached it in a different manner. It was not replaced). This took away the CEL light for about 3 days or so, until the weather got cold.

    Or are there actually 4-5 legit causes of the CEL coming on?
    Again, for me, yes. I've had 3 gas caps put on; had a repair to the purge valve; had a repair to the gas fill neck; and had the IMRC valve worked on. So in my situation, yes, I've had the CEL come on for a variety of reasons! Certainly other drivers might be having a different experience. I live in Connecticut, and I did a very brief check of our lemon laws. On the surface it seems to read that treating the car 4 times for the same thing (over a 2 year period, I think)would fall under the lemon law. Therefore, I can't avail myself of the law as of yet (if I'm reading it correctly).

    My CEL's been on full-time for over a week, as our temps have been in the single digits/teens for a while now. I'm simply ignoring it and am pretty sure it'll go out once we get above freezing. That's been the drill so far this winter. Is that acceptable? No. Do I have the time to get to my dealer (who's NOT open on Saturdays)during the week, thereby missing work every single time the CEL goes on? No. Therefore, I'm doing nothing. I'll deal with it at the next oil change.
  • vbbuiltvbbuilt Posts: 498
    Well, if this helps, I've had CEL 4 times.

    1. Purge Valve (part #L33L-18-740) at 3063 miles
    2. Gas Cap at 5249 miles
    3. IMRC valve (code p2006) at 11314 miles
    4. Code P2006 IMRC out of adjustment. Reflashed PCM at 12036 miles.

    I'm at 15500 miles now and no CEL since the 4th occurrence.

    So, knock-on-wood, fingers crossed, I've had all the common CELs and maybe, I won't have another issue for a while? Although, I've had the car since early June 06, I have to admit I'm not that aggravated. In a nine month period, I've only had to visit the service department 4 times (those 4 visits also included oil changes and prescribed maintenance checks).

    In my case, considering that this is the first release of a new model, I'm pretty satisfied with the vehicle.

  • astegman, I also live in CT and my dealership in danbury is also not open on Saturday. Plus I work 1/2 hr. away from danbury and then it is another 1/2 from there home. If I had a dealership near work, bringing it in 5 times would not be as big a problem as it is for me......My dealership also mentioned the gas fill neck fix as the next step which may be an absolute waste of time.....The reason I lease is to avoid trips to dealership / repair shops.......
  • astegmanastegman Posts: 171
    johnny_rf, I live in Ridgefield, so I'm assuming we are both dealing with Colonial Mazda. I work an hour away from them in the opposite direction (down in Westchester), so it is a major inconvenience to go up to Danbury (20 minutes from home), have the car serviced, and then drive an hour down to my office. Other than not being open on Saturdays, I think they've been great so far. Just FYI, the dealership in Bedford Hills (NY) is open on Saturdays, but just for oil changes - I don't believe they have any mechanics on duty those days. Anyway, I can no longer lease cars because I drive so much and cannot stay within the mileage limits. So I had to buy a car last year when the lease on my last car finished.
  • Yes, I also use Colonial. Service manager was great. They were very accommodating for my first visit allowing me to bring the CX-7 in for a 3:15 appointment to do the diagnosis and they had enough time to replace the gas cap while I was there. I was told for the fill neck, I would have to leave the car and get a loaner. Have they been giving you loaners for your visits? I'm assuming they use Enterprise right down the road?
  • "That's the 3rd or 4th time you've said "I'm done with this topic." These forums sure are addictive, aren't they?"

    I believe I only said that twice, and I mostly keep responding because it seems whatever I say gets misquoted.

    I'll make you a deal, don't respond and neither will I. Hopefully you can fight your addiction and won't feel compelled to respond


    "The gas cap issue is a ringer of a situation.

It just so happens that the gas cap is by far the weakest link in the system and most probable issue when a pressure loss is reported by OBDII."

    While that's obvious and true, if you got a gas cap error due to a loose gas cap or pressure loss, that would be a starting point. If tightening the cap doesn't do it, then the next step would be contact the dealer.

    "FWIW, I don't blame anyone for not wanting to know how to change their oil - but assuming the vehicle manufacturer had a decent design to start with, not knowing how to tighten a gas cap is really inexcusable."

    It may be inexcusable, but it happens to more people than you realize or might care to admit... and what about those states like New Jersey that insist on pumping your gas for you. Do people always get out of a car to make sure the attendant tightened the cap.

    In any event a gas cap is just one example and issue. I still cast my vote for something better than a CEL on my display.

    Technology is changing very fast, but in the automotive world some of the technological advances are being hampered by politics and the competitive market. Just think back to every time you exchange a car for a new model at all of the features and technologies that are being incorporated. Some of the changes are not always welcome or what we expect, but that's just the way it is.

    That's all for now.... I have "The Last Word" and I ain't giving it up.
  • No deal. It IS an addictive forum and I never claimed I was done. :P

    "While that's obvious and true, if you got a gas cap error due to a loose gas cap or pressure loss, that would be a starting point. If tightening the cap doesn't do it, then the next step would be contact the dealer."

    No, I'm not quoting you when I say this - but it really sounds to me like you want a gas cap warning light that may or may not even represent the actual problem with the car. IMHO, that is not an improvement over the idiot light you have now.

    As far as things humans do that I'd rather not admit - there's plenty of Darwin-award-worthy happenings out there every day. Still doesn't mean we should accept it.
  • astegmanastegman Posts: 171
    So far, I've waited at Colonial each time and thus haven't needed a loaner. I agree, the manager is great (Jeremey, right?). This is off-topic, but Jeremey's wife works at the Subaru dealer in Brewster, where my husband takes his Forrester. We were there last week to pick up his (my husband's) car after a routine servicing, and Jeremey was there - he recognized me and was very nice.

    "a gas cap warning light that may or may not even represent the actual problem with the car"

    I think a gas cap warning light would be good - when my car throws off a code, there may be 6 or 8 things to check when you look up the code in the book (and often they want you to check seemingly unrelated systems).

    I suppose it's cost prohibitive to have a 1,000 sensors feeding info back to the car's computer but maybe better software will come along that help narrow the codes down some.

    The display on my dash should just tell me to go fix the gap on my #6 cylinder sparkplug because the ECU has figured out that the compression is 5% lower on that one and the emissions and O2 sensors correlate the diagnosis. That's not too much to ask is it? ;)

    Come to think of it, the ECU should just tell the wiring to that plug to compensate for the out of spec gap.

    In fact steve, you need a Trunk Monkey that will fix your truck at each stop...and beat the cr*p out those that get in your way. ;)

    When I think about this discussion, I always come back to the office copy machine. They've gotten much better over the years with scan, fax, binding and printing support, but the only errors you get are: clear a paper jam (like your car telling you to pull a cat out of your fender well) and call Canon for service. I'm a fairly technical and intuitive guy, but I wouldn't go beyond clearing a paper jam or an obvious fix without a full manual and the tools that go along with it. My work chooses to have Canon come out fix them when needed and not a third party. I'm sure they've considered the cost...
