#1622 of 2771 Re: O2 Sensor on 2001 Pathfinder [ftd]
Aug 18, 2005 (9:18 pm)
Bank 2 means it is one of the 2 rear O2 sensors. Interestingly, the rear sensors are not used at all to control fuel input unless one of the front bank 1 sensors fail. If a bank 1 & bank 2 sensor failed you would go to a full rich mixture & your mileage would suck. But as long as this is the only one out you won't see any effect. Sensor 2 is the one on the left or driver's side. I just replaced this sensor without too much trouble. Don't buy from dealer or Autozone for $100s, I bought from www.bosch4less.com for much less and this is the same OEM part. Unplug the harness connector under the hood & pull the clips loose that hold the cable in place. Unthread the sensor using a wrench. You won't need an O2 sensor socket for this one because there is room to access it with a wrench. Once removed apply anti-seizing compound by brushing it onto a thread chaser & threading it into the socket. I priced several chasers, including the one from Nissan's tool supplier & they were really expensive. I bought one at Autozone that's labeled a spark plug thread chaser & is two sided for like $5. I can't remember the pitch & size you need & I'm not at home to check my service manual but I think Autozone only had this one chaser. After that plug the new sensor into the harness & lower it through the opening. There are clips to pop into prelocated holes along the route to keep the cable in place. This was the only hard part because the last couple of clips are a pain to reach. Finally, just thread the new sensor in & tighten it carefully. I had the dealership reprogram my ECM like you said but they wanted to see the receipt showing that I had changed the sensor because the TSB calls for this first. The $40 I spent was much better than the $100s I was quoted. Good luck.
#1623 of 2771 intermitantly won't start - '96 Pathfinder
Aug 19, 2005 (3:52 am)
My '96 Pathfinder, manual, 4WD with 180K miles has begun to randomly not start. It's happened twice in about the last 6 times I've tried to start. The first time I checked under the hood (looking for what, I'm not sure) and noticed that the one battery terminal had significant corrosion, so in true kick-the-tire fashion, I knocked off the corrosion, got back in the truck and it started up like a champ. Drove directly to the auto parts store, had the battery tested and was told it was no good, so I got a new battery. Ran a couple errands last night, started up with no problem. Started this morning just fine, stopped to get coffee, came out and wouldn't start. Turned the key again, wouldn't start, did this a few times, still wouldn't start. Sat there a few minutes wondering if I'd just replaced a perfectly good battery... then turned the key and started up like a charm. When I turn the key and it doesn't start, there is no clicking and no noise like the engine is trying to turn over. All the dash lights & radio come on. It's the same result as when you turn the key and don't have the clutch in... I owned an '86 nissan pickup that had an Interlock switch that would over ride the fact that the clutch wasn't pushed in and you could still start the truck (enabling you to push start if needed). I don't see this on the '96.... any ideas if there's an equivalent on this year truck so if I get in a bind I can at least drift start? Any ideas on what the true problem may be? Thanks in advance for your help!

My 2005 Pathfinder goes into the Nissan body shop next Wednesday for RUST beneath the chrome strip above the rear license plate. Only have 6000 miles/9 mos. old. Anybody else seeing rust?!?!

#1627 of 2771 SES Light P1140 Code
Aug 21, 2005 (11:53 pm)
Doing some reading on the is board about the problem, but trying to understand what sensor it is (L/R). So it's the cam sensor that needs to be replaced, but some say it's the right side (passenger side), some say it's the left side (driver side), so I don't know which to buy (I'm going to replace it myself).

P1140? Are you sure that's the code? How did you get the code read? I couldn't find P1140 in the service manual, either. What year is your Pathfinder?
The camshaft sensor code is P0340. See this link for all OBDII trouble codes.

Yup, P1140 it is not a generic code, Nissan specific. Pulled it from the code reader directly. It's a 2001. Some sites say Bank 1 is LH, some RH that's what confusing me. Reader is from EQUUS.

#1630 of 2771 1997 pathfinder noise diagnosis
Aug 23, 2005 (1:03 pm)
I have a 1997 pathfinder, 5 speed manual, 4 WD, with 126,500 miles. I am trying to decide whether to keep the vehicle, which I like a lot. It needs new tires and exhaust work, and has a knock sensor problem and a minor coolant leak, I believe at a gasket associated with the intake manifold. Also, the CV boots are starting to crack. Recently, I have been noticing an unusual sound at low speeds. It is intermittent, and does not happen when the car is not moving. It seems to be worse when the car has been parked for a while. It is, like all sounds, hard to describe, but sounds kind of rubbery, like scraping or clunking. It comes from the front end. I have not noticed that it correlates with hitting bumps, releasing or depressing the clutch, shifting gears, etc.
Any thoughts what could be causing this? I am sitting on the fence whether I should get the tires and exhaust work done, but will probably get rid of the car if this most recent noise is something serious. My dealer told me not to worry about the coolant leak or knock sensor; just to use 89 octane gas and keep an eye on the coolant level.
Any thoughts about the noise and the wisdom of hanging on to this vehicle greatly appreciated.
#1631 of 2771 Strange Noise at 45 MPH
Aug 25, 2005 (5:45 am)
I have a 199 SE Pathfinder. When I drive on the highway and the car shifts at about 45 a screeching sound (not a belt sound) comes out from under the car and then goes away as the car accelerates to 50 and beyond..Has anyone ever had a such a thing. My mechanic mentioned some cap on the undercarriage?
