Nissan Pathfinder Maintenance and Repair



  • The same happened to me... I went to local body shop for oil change and explained the same sound situation and he tightened the engine belt and now I don't hear that sound again....

    Hope this helps...
  • can anyone tell me what I might look for on my 97 pathy???? failed the state test with 3 codes, po446, po443 and po450, changed plugs and pcv and the first 2 codes went away, the ses came back on shortly with just the po450, any help is appreciated.

    Refer to post #1217 for info.
  • my SES light has been on for about 3 weeks. I pulled the codes and it showed 1135 (intake valve timing control circuit-bank 2) and 1110 (intake valve timing control solenoid). The engine seems to be running fine. Has anyone else had these codes before and is this a "do it yourself" job and where would I find parts? Also, any idea on cost and where these parts are in the engine. Thanks.
  • I have an 05 frontier with the vq40 engine and the rattling noise at 2100 RPM. I took it in today - they had not heard of this problem - but within two hours of leaving the dealership, they said Nissan is aware, and they ordered a new intake manifold, gasket, and some adapter.
    I'll let you know if this resolved the problem - I think it will.

    I had the 1135 code but it went away by itself after a week or so. Time may depend on things. Wait a few weeks and a couple tanks of gas from different gas stations to see if it will reset. If it is an immediate safety or poor performance need then by all means address the issue but, I would give it some time.

    Sensors are relatively easy to replace but not yet though....Haynes repair manual shows you how.

    SES light may come up again because it may not be a real code and then you wasted time and money for parts.
  • I have a 1996 pathfinder and it has the same problem gas mileage sucks and no acceleration on the highway I was told it could be the fuel pump but I checked the pressure and it was 34 psi Some body told me it could be a blocked catalytic converter I don't know can any body help???

  • Are you using premium gasoline? If not you are lowering performance and MPG. As for the loud engine, did you not test drive the vehicle?

    After 1 day, the SLIP and VDC lights went off. The SES remained on and I had to take it back to the dealer. The mechanic explained he couldn't tell what the malfunction was because several cycles passed before I was able to bring it in. So far all malfunction lights are still off.

    Also, in my search to discover a reset procedure I noticed the manuals on line and in print are different. The manual that came with it referenced a reset procedure that was no where to found. I checked the online pdf manual and I found it.

    It would be of great help if you could let me know if the rattling noise was resolved or not. Thanks
  • rs4, I'll be glad to post an update. Hopefully it'll be good news. The new part is scheduled to be installed on the 2nd (Wednesday). I'll probably give it a day or two after that to see if the problem persists, and then I will post an update. I do know of another person who had this done, and it fixed the problem.
  • I have a simular problem, have you managed to fix it yet, if so how did you manage it.....
  • rs4rs4 Posts: 25
    Thanks woodshop28 I will wait for your post. I too hope the problem gets resolved. All the Best. Oh thats good to know, that it did work for some one. Thanks again

    I have a 2001 Pathfinder LE 4x4 also(53K miles). My SES light came on about a month ago. I took it to Autozone to get the error codes. They were P0420 and P1140. I was thinking it may be the O2 sensors. When I checked with PepBoys (they usually have reasonably priced auto parts), 3 of the4 sensors were $350 each, the other was $80. I was wondering where you found all 4 sensors for $300?

    Does anyone have any other suggestions for correcting these error codes? The codes were cleared when I checked the codes, but it came back on my 3rd trip and remained on ever since.

    jmfjr, see post #1240 above, it's likely you can get this repair completed under warranty.
  • smokey75smokey75 Posts: 434
    I'm going through the same problem and don't count on getting it repaired under warranty. The TSB regarding this says to replace the oxygen sensors (only covered under the 36,000 mile warranty), then reprogram the ECM (covered under the 70,000 mile federal emissions warranty). The dealer I took it to told me to bring in a receipt showing that I had replaced the oxygen sensors & they would reprogram the ECM for free... or I could let them replace the oxygen sensors for almost $600 parts & labor... no thanks. I too checked autozone & the price was much more than the dealer. I found them cheaper online several places. Just do a google search for "2001 Nissan Pathfinder oxygen sensor."

    Could you let me know who is the dealer that is trying to solve your problem.
  • kashkash Posts: 2
    Hi guys, the rattling noise at 2000 to 2100 rpm needs to be resolved. Somebody who had their manifold replaced and did not resolve the problem, should call nissan and open a tech case. After they should post the contact number at nissan so we can all put in a tech issue with the same person. Then nissan will be aware of the problems we are having with 05 pathfinders.

    hi Pathfinder owners,

    I notice a lot of noise when driving my 99 Pathfinder at highway speeds. Seems to be coming from the roof area. It has a sunroof, but no wind deflector.

    If I install a wind deflector, will that likely help ? I've installed them before - very easy, but why spend the money if it won't help prevent noise ?

    Sure appreciate a word from someone that has solved this problem.

    Thanks, John

    2005 Pathfinder LE owner here.. I just did a google search on "2005 Pathfinder acceleration rattle" and hit your forum. I guess I'm not the only one with this problem. Here's something I noticed, when alomost out of gas (25 miles to empty) the rattle disappears and the engine seems to run better. Am I on crack... or is there something to this almost out of gas thing? BTW, I took mine to Nissan for the rattle and they claimed they "could not duplicate the noise". Hmmmm let me help you by removing that doughnut from your ear and kicking you in the @3&;&!! Any more progress on this issue anyone????

    I have a 2002 Nissan Pathfinder SE 4 wheel drive, just about to turn 50,000 miles. I love the truck and have had no problems with it, but I am starting to wonder if it is burning oil.

    On rare occasions I have noticed upon startup that I get some blue smoke out of the tailpipe. I have noticed this maybe 3 or 4 times over the 3 years I have owned the truck. Last time I got an oil change I noticed on the ticket afterwards they had noted it was a quart low. I use synthetic oil and usually change it about every 6,000 miles as I do 90% highway driving.

    I am almost due for another oil change, but this morning I noticed the blue smoke after starting it, so I drove for a few minutes, then parked it for a few minutes and then checked the oil, finding it is a bit low, below the cross marks on the dipstick. I am guessing it is about a quart low again.

    I am wondering if this is a bad sign and if anyone else has encountered this problem with the Nissan 3.5L V6 engine. I love the truck but don't want to keep it if I am going to have engine problems from bad rings or something down the road.

    Any thoughts anyone??

    If you see smoke on startup it's usually caused by the valve stem seals leaking. The oil seeps into the combustion chamber and burns on startup. It can be an indication of worn valve stem bushings. This loss area usually doesn't use up much oil - you shouldn't notice the loss on the dipstick, even over several months and 5000 mi. - the loss is very small past the valve stems.

    It is also possible a head gasket is leaking or the intake manifold gasket (if there is an oil galley through it).

    My oil is usually down almost a litre after 6000 km and the vehicle has done this from new. If you are down just a quart close to change time I wouldn't worry about it until it gets a lot worse. If you have to add a quart half way to change time then worry.

    Are you using 5W30? That can contribute to oil use. I switched to 10W30. The engine sounds quieter and runs smoother. I use Mobil 1.

    Well add me to the list of folks with the "2005 Pathfinder acceleration rattle" problem. I'm schedule to have it repaired this Friday. Though the service manager said it was a rare issue, she did say they do encounter this situation periodically. She indicated that it was a catalytic converter issue. Let me see what the dealer can do. I've had the issue ever since I turned over 500 or so miles.

    Not sure if you are still checking this forum, but I had the same exact problem with my pathfinder as soon as I drove it off the lot. There is a reset procedure in the manual, but it doesn't work. It says to start out w/the steering wheel straight and then drive for over 10 minutes over 10 mph. The most ridiculous thing I've ever seen. I did it 5 times and it didn't work.

    Brought it to the dealer and it stumped them for 2 days. Then they decided to run the car in place on a lift in the service bay (as per the reset procedure) and that supposedly reset it. The dealer said that is how they are going to have to reset it and if you do a couple of things (including change the brakes) they will need to reset the system this way.

    I'm hoping that is just the dealer not knowing the new car yet b/c if that's the case then the people at Nissan must be out of their minds. Anyway, that was my experience, hope it worked out for you.

    rufus19, I switched to Royal Purple Synthetic ATF, which may have resulted in a slight improvement in cold shifting. Then again, this may be a placebo effect. My best solution has been to allow the vehicle to idle for a few minutes before driving. Let me know if you have any other insights. winxsd
  • The parts did not get to the dealer in time for my appointment. As soon as it gets there and it is installed, I'll post an update.
  • rs4rs4 Posts: 25
    Thanks for the update.

    After having my car in 3 times, my dealer let me know that a butterfly valve on the manifold is the culprit. According to the service manager, it was a design flaw. Nissan is aware of the problem and has a redesigned manifold that I had put on 3 weeks ago. Since then, the noise has not returned.

    Has anyone been hearing a rattle in the plastic sunshade for the moonroof?
  • opiedogopiedog Posts: 9
    Okay, I let the dealer have my Pathfinder all day today. They changed the catalytic converter and nothing has changed. The mechanic agrees that at just about 2100 rpm there is a tinny sounding noise coming from the engine. It is even audible when the engine is revved with the brake on and the vehicle is not moving. The mechanic is going to contact Nissan and I will be dropping it off again on the 7th for further work.

    Hey all, thanks for all the info on the problems you're having. We have an 05 and have not experienced anything (well, the brakes squeek, but that will subside), so I want to ask my dealership what they're hearing on any of these problems. Let me know what your resolutions are and if I hear of anything from this end I'll post it. We still love our choice (05 SE 4x4).
