  • I don't know if this is your problem or not. But I had something similar on my '03 MPV. Turned out to be a cracked PVC pipe, which was on recall. We went to one dealer who didn't have time to help, and I called another dealer who recognized the problem right away and had it running back to normal.
  • I have been noticing a hot smell from the front passenger side of the engine. Sometimes it smells like sulfur. Around the time it first occurred a week or so ago, the check engine light came on and has stayed on. Could this be a PCV or some other component?

    It is definitely a sulfur smell, and not a burning smell? If you are in the snow belt, there is a possibility that your alternator could be going bad, but I don't think that it will trigger a CEL. Did you get the code read at AutoZone?
  • It was only a sulfur smell once. Last night after driving from Columbus to Cincinnati (100 miles) it was just a burning smell on the front passenger side under the hood: the alternator is down under on that side. Hmmmm. No, I have not had the code read at Auto Zone. Do you mean the parts store?
  • nlsnls Posts: 65
    Yes, the parts store - they read codes for free and tell you what it is, so that you will buy any needed parts there. Other shops will charge you a lot for doing the same thing. My alternator lasted for about six months after the first episode of very bad electrical burning smell, but CEL usually does not come on with an alternator problem - mostly the battery light.
  • Thanks, I will have the code read and see if I can narrow the problem down.
  • Hello - I just experienced a problem with my '01 MPV, idling low and behaving as if it were misfiring, when stopped in drive gear or in park. Seemed to be just fine once it came off of idle. Turned out that the air intake manifold gaskets were leaking badly. I had these replaced and it took care of the problem. Also improved power and my highway gas mileage increased 4-5 mpg. I bought the van used and always thought the mileage was terrible. This explains why. However, it took awhile until the condition deteriorated to the point that if affected engine performance at idle.
  • I have had my MPV to the dealership six times for a P300 code. The first trip they diagnosed it as an ignition coil problem. They replaced and it ran fine for two weeks and then happened again. Checked it out and said the part they put in was faulty. Kept for two days and drove okay for another two weeks and then same problem. Today the pulled back the carpet on the passenger side, exposing the computer and wiring harness and indicated that there was a crimped/loose wire. Taped it up and sent us on our way. 30 minutes later, same problem. Has anyone else had a wiring issue related to the ignition system? Should this be a hard problem to resolve since they have indicated that they know exactly which wire it is?? Lastly, I believe that their original repair was not required, that it has been the intermittent wiring issue all along, but they don't seem to be listening to the logic of this. Any ammunition that can be provided??

    Hi, lamc -

    Have you had any luck with your starting problem? I've been experiencing the same problem for the past few weeks - and, of course, at THE most inconvenient times! Have had the 2000 MPV at the dealer, but again, of course, the van started right up for them every time...

    :mad:

    Thanks!

    My used 2001 MPV has an odd problem - after a heavy rain, you can hear a "sloshing" noise coming from under the seat area (the interior of the car stayed dry, though). After some heavy rain, late this summer, the sloshing sound didn't stop for quite some time & now the entire van smells like mold & mildew! It is at its worst under the back-most/roll down seats (when you open the hatch, you want to hold your breath!).

    Has anybody else come across this/does anybody have ANY idea how to fix it.

    Thanks!

    The problem is supposedly due to the blockage of drain holes causing water to accumulate, but I don't know all the details.

    See posts 2525, 2523, 2443, 2439, 2260 and 2047. They might help you in tracking down the problem.
  • I have a 2000 MAZDA MPV with 72k miles on it. This vehicle has the exhaust manifold integrated with the converter, the 2 can't be bought separately. It actually has 2 manifold/converter pipes, one onthe left one on the right. The one on the right has developed a hole (NOT a crack) in the pipe, in a wend near where the gas leaves the engine. 2 questions:
    1) Would this part be eligible for the 8 yr/80k emissions warranty? The converter box looks fine but you obviously can't replace the manifold pipe without pulling the converter
    2) How do I approach the dealer on this?
  • my 89' mazda mpv has 212k i pushed on the throttle and it had no power when i put it in drive or in reverse please help

    I'm confused with your problem. If you are stopped at a traffic light with the engine running, yes you must keep your foot on the brake or the car will move forward. This is typical of any automatic transmission. It sounds like you are taking the car out of gear (putting it into Park) each time you stop at light. So it takes you longer to move once the light is green, thus all the horn blowing behind you. No need to do that. Your car is operating jsut fine.
  • My 05 Mazda MPV with only 1200 miles is getting about 16 mpg (equal mix of highway & city driving). Is this normal? Also, dealer punctured a hole in the headliner while installing the roof rack. The new headliner has been on order for 2 months now. Is the dealer playing games with me? :mad:
  • jipsterjipster Posts: 5,345
    I don't know if they are playing games with you...but it sounds as if they are fairly incompetent. I could paddle a canoe to Japan, pick up that headliner, and be back in 2 months. May want to try another dealer if possible.

    19 mpg is the average combined city/hwy. See if you can get a highway only mpg(should be around 25mpg)...your city driving may be bringing it way down. Check tire pressure and driving habits(i.e slow starts and stops, no speeding etc)
    Engine may still be breaking in, so should improve some with another 3-4k. Have dealership check if still no improvement(when they get that headliner in)
  • Re your gas mileage. I bought a used 2001 MPV about a year ago and always believed the mileage was poor, but since I didn't buy it new, really didn't have a good reference. It would typically get 18-19MPG on the highway, sometimes 16MPG in the city. The problem was eventually diagnosed as leaking air intake manifold gaskets. Once these were replaced and the leaking was stopped, our highway mileage went jumped to almost 23MPG and the city is now about 20MPG. Keep in mind that the vehicle seemed to be driving normally otherwise, but we have also gained additional power with the system tightened up, as you can imagine. And, this vehicle had been to a dealership with other issues and no one "discovered" the leaking air intake, was not setting a code. It just deteriorated to the point that it began affecting my low idle, so I knew I had a problem of some sort.

    Our 03 LX with under 40K miles has never brought more than 15 MPG, city or highway. Now that winter has cooled us off a little (Houston, TX) it's gotten a bit better, but nothing major. Will definatelly never get more than 260 miles to a full tank. I check tire pressure routinely, I use synthetic oil only. We've been through about five returns to dealers, they insist this is the normal mileage for an MPV. I've given up, looking at a Tahoe....... roomier, safer and believe it or not, much better mileage (16/22) than the MPV. :lemon: ???
  • HELP! Any advice would be appreciated.
    PROBLEM #1 - Our 2005 MPV has right sliding passenger door that will not shut automatically by itself. You know the problem, it doesn't sit flush and opens itself up. It's been in the Mazda shop (under warranty) four times and they can't seem to fix it. Any success stories out there on how Mazda fixed it?

    PROBLEM #2
    This is the one that has my wife freaked out. Periodically, the right side door will attempt to open by itself while on the road. Actually, you can hear the motor cycle through, but the built-in safety features prevent it from opening up on the road. Mazda claims they have never seen this or heard of it, but there is no denying it, the motor cycles when driving down the road, which tells me it is trying to open.

    I think the problems are related, but as you can imagine, the Mazda repairman can't seem to replicate the problem, or see it/hear it happening. ANY similar instances out there?

    Anyone out there try replacing the DRIVERS SIDE headlight yet?
    There are two corded wires that are taut and go in front of the rubber boot for extracting the bulb. I read the manual and there is no way that bulb is going to pop out the way it states. It's like they ran all the junk in the hood around after the bulb was put in and routed two large cords of wires right in front of the opening!

    Lovely, I'll need to PAY MY DEALER to install a stupid light bulb for $60 labor I'm sure!!

    Another stupid 'feature' on this vehicle that goes with the unbelievable bone-head design on the rear tailgate license plate lights. Wait until you need to replace them! The dealer went nuts trying to figure out that the inner panel had to be removed!! The lenses don't just 'pop out' like the manual states....again!

    Again, any experienced owners with this light replacement activity; please come forward. I'm all ears!!

    Dealer would be extreemly stupid if they did not try that yet, but try it anyway, to clean the contacts on the side of the sliding door and on the side of the B pillar as well (thos metal circular rods looking things).
  • lazyfoxlazyfox Posts: 90
    Quite crowded in the front for removing those headlight light bulbs, but the rear tale gate license plate lights pop out as described in the manual, but you have to be careful not to brake the plastic clip as I did, but nothing unfixable, I just used a tiny screw to fix that.

    Thanks for the nice pics on the process. Again, the dealer had a problem removing those lenses and opted for taking out the inner panel on the tailgate to get at them. He did not charge for the replacement FOR THE FIRST TIME anyway!
    Yep, those headlamps are a pain!!
    Too bad newer cars are designed by great engineers who have never done the work themselves!! Job security for the mechanics for sure!
  • Whenever we have a foggy, high humidity morning, when the van is first started, it accelerates roughly in the lower gears, until the engine warms up. I don't know if the engine is missing or something else, but the vehicle is definetly under-powered initially until things heat up. Anyone else have this experience and been able to correct?
  • crissmancrissman Posts: 145
    If you haven't done it already, a real mechanic would probably recommend new plug wires at a minimum and that it likely needs a full tune-up.
  • Thanks - just recently replaced the ignition wires, plugs and coil pack because of another unrelated issue.

    I have a 2003 MPV LX with the rear a/c & heat control. Just recently I've discovered that I can no longer control the temp of the air coming out of the rear from the front console. It seems that it only responds to the temp setting in the rear console. I can still control the fan level from the front for the rear vents but that's about all the control I have from the front. I know it used to work fine before, because my daughter would be in the captain chair and I'd give her either a/c or heat. Has anyone else experienced this prob. I should take it to the dealer since it's probably under warranty, but I've just been lazy. Also the A/C gives off a lot of smell when I first turn it on. It's an annoying smell, but it goes away after the a/c's been on for a little bit. Besides these 2 problems my mpv's been pretty reliable. Going on 34,000 miles.
  • subearusubearu Posts: 3,613
    If your MPV was allowing you to control the temp from the front, that's an anamoly. The only control the front has is fan speed - and the AC since if it's on (or off) in the front, it's on (or off) in the back.

    RE: the AC smell: You can try cleaning the AC condensor with Lysol (or equivalent). I think there is a TSB for cleaning it. One way to help prevent it from happening is to turn off the AC a few moments before you arrive somewhere but leave the fan on to help dry the moisture that has accumulated.

  • So there I was needing a vehicle in better shape than I had and a friend says You know..... you can have my Mazda MPV. It has oil in the rad so probably has a blown head gasket. Oil is fine, compression is fine, works well except for oil in rad. Ok I take the van home and learn the joys of replacing the Head gaskets. Lots of advice from mechanic friends and followed the Haynes manual explicitly. Made sure the timing belt was just right connected all the tubing just the way it came apart. Checked the heads for flatness replaced all the gaskets and have the engine all back together again.

    Engine won't start. Cranks well no spark. Engine codes say prc solenoid and no ignition signal. Test PRC solenoid all OK, no spark. Find disconnected shutter valve actuator reconnect. Zero out engine cpu. Restart good cranking no more engine error codes still no spark. New plugs, new High tension wires all connected in correct places. No spark from coil. Test coil. Coil tests OK.

    So what do I do now?
    Is the Igniter prone to breaking, Is the CPU prone to breaking. Can the Igniter be tested. Is there anything I can do without taking it in to a dealer as money is an issue.

    Any suggestions?
