#8004 of 8191 Pathfinder02 (PF'02) maintenance questions
Jan 20, 2006 (10:45 pm)
I simply love my 2002 Pathfinder LE, currently 66000 miles, that I bought 6 months back, but dont know much about its maintenance. I need advice from the experts in the forum on some maintenance and performance questions. I would really appreciate any inputs.
1) "Service engine soon" light is on (yellow). I got a diagnostic done and the codes are P0159 and P1167 - actions needed are ECM reprogramming and replace rear oxygen sensors (banks 1 and 2). Earlier, dealer said that the light was due to evap leak and got the light tripped off but it came on again. Can I get reprogramming done by Nissan under warranty (8 yrs/80k miles) and also what is approximate cost for replacing oxygen sensors?
2) The transmission fluid is clear and the mechanic told me it should be pinkish. He said I urgently need a transmission flush. Is this correct? I checked PF'02 manual and it says about automatic transmission fluid (ATF) but does not mention color. Should this be done only at dealer or can I take it to any automotive service store?
3) The mechanic said power steering fluid is not clear and I need a power steering flush. At what mileage is this required and do I really need this - meaning should I look at the level also or just the color? Same question for the radiator/coolant flush?
4) The mechanic also told me that I need new fan belts (both need to be replaced). How I can check that the current ones are in really bad shape? Also at what mileage do these really need to be changed for PF'02?
5) When I shift gear from P (park) to R (reverse), the vehicle's rear tends to dip downwards a little (whether in 2WD or in 4WD). I can feel this in the driver's seat. Is there some major problem or is this ok? Could anyone please explain why this may happen?
6) When I shut off the ignition, there is a thud sound and the vehicle shuts off in a jerky movement. Could anyone please explain why this happens and how this can be fixed?
This is my first post on this forum and I would really appreciate any details on my above concerns. Thanks in advance.

1)I don't have my service manual with me but P0159 I believe relates to either the left or right rear oxygen sensor, but not both. There are a few things that could cause it (short in cable, etc.), but most likely you need to replace that sensor. From the dealership they are hundreds of dollars plus labor. You can buy the original equipment sensor at www.bosch4less.com for $50-$100. The ECM reprogram probably relates to a TSB that changes the oxygen sensor monitoring parameters. That is covered under the ECM part of the emissions warranty, however long that is (I dont' have my manual with me). But, the TSB says to replace the sensor first so if someone else does that you may have to show them proof that it's been done. My dealership had me show them the receipt for the sensor. Not sure about 1167 without my manual here.
2) I've never heard of clear transmission fluid but I can't swear it doesn't exist. It's usually pink & turns grayish as it get dirty. Anyone can change your fluid, not just the dealership.
3) The power steering uses transmission fluid so this should also probably be pink. The manual doesn't specify when to change it & I have not yet with 75,000 miles. Anybody have ideas about this? Most people recommend your coolant be changed every 2 years.
4) I replaced my belts at 60,000 miles. Yours may be cracking or glazed over.
5) Not sure
6) That may be the transfer case disengaging if the 4WD is in AUTO. If that's all your feeling it's normal. After driving put the car stop & put the car in park and leave the engine running. See if after 30 seconds or so you feel the same thing.

1) P0159 and P1167 are O2 sensor codes. See all Nissan OBDII codes here. Not sure how much they cost, as I've never had to replace mine yet.
2) ATF is cherry red, like cough syrup. It becomes brownish as it ages. It should never be CLEAR!
3) Power steering fluid and ATF are usually interchangeable. That is, you can usually use ATF instead of power steering fluid, but not the other way around. Some P/S fluid is clear. Perhaps that's what someone put in your transmission!
4) Like smokey posted, check the belts for cracks or glazing on the inside (ribbed) surface.
5) This is just the drivetrain torquing, which causes the rear suspension to move (since the brakes are preventing the rear wheels from turning). This is nothing to worry about.
6) smokey's post is right on the money. It's the auto-mode system disengaging. Use 2WD instead of Auto mode and the lurching condition will probably not happen.
#8007 of 8191 Tires for a 1999.5 Pathfinder
Jan 24, 2006 (9:18 pm)
Hey everyone, I just moved to Colorado about a year ago and it's time for new tires on my 1999.5 Pathfinder. Any recommendations??? Right now I have Deuler HTs on there, but they are pretty expensive and I'd rather not spend the money to get the same ones if there is a cheaper alternative. Thanks!

What kind of tires do you want? Highway-only? All-terrain? How long do you expect them to last?
Check out tirerack.com for some ideas on what looks good.

Appreciate your participation here, both on this subject & one a few days ago.
I don't need tires yet, but will in the next year or so. I live in AZ, where there are excellent off-road adventures to be had, and we've done our share. OTOH, the vehicle spends 99% of its mileage on pavement or gravel & we don't take four-wheeling seriously enough to have a dedicated set of off-road tires. We air-down and crawl some pretty decent rocks.
So, from your perspective, what's a decent tire that spends most of its time doing mundane things, but can deal reasonably effectively with off-road stuff -- generally no mud, but lots of rocks and ledges. I'm in Sedona (on vacation) as I write this.

I'm mostly looking for an all-terrain tire. I do some 4-wheel driving, mostly driving through the mountains to ski resorts (so through ice and snow)/camp sites, etc. I replaced 2 of them about 3.5 years ago (approx 35,000 miles), I'd like them to at least last that long.

Check out either the BFGoodrich All-Terrain T/A-ko or the Bridgestone Dueler AT Revo in a 31x10.50R15 or something a little larger in size than your current tires. Both are good all-terrain tires.
I used to run BFG AT's before I swapped out to mud-terrain tires for extreme 4-wheeling. The BFG's lasted over 40,000 miles with mixed city/highway driving and a fair bit of severe off-road use.
#8012 of 8191 My pathfinder has no power after replacing water pump
Jan 30, 2006 (8:23 pm)
The water pump on my 1994 Pathfinder(4wd) went out and my mechanic replaced it. Since replacing, it has no power. Very sluggish taking off and will not climb hills very well at all. Not good since I live in the Ozark Mountains of Arkansas. It sometimes has a sound like an intermittent hiss from the passenger side of the motor. It also surges at times while accelerating and while maintaining speed. My mechanic is baffled! Can you help?

Sounds like the timing could be messed up. Did your mechanic change the timing belt along with the water pump? If so, he may have put the belt on incorrectly (off by one tooth).
Also, if your water pump failed, there's the possibility that the engine was damaged due to overheating.
Check-engine light on? If your mechanic is baffled, you might want to get a second opinion elsewhere, possibly at a shop that has emissions-testing equipment, which allows them to do a more thorough diagnosis.
