    It's the drivers side after the cat. I purchased a ODBII tool and bought the O2 Sensor online. Much less expensive than the dealer! Fixed in a few minutes!

    can you tell me where you bought yours so i can do the same procedure as you? how much was it? also, do i need the ODBII tool, and where can i buy that, or will the computer reset itself once the oxygen sensor is installed?

    my code says:
    P0158 Rear O2S, Bank 2

    i think it is:
    part # 226A1-4W011

    can i reset with this procedure?:

    I purchased a "Scangauge II". It can read and reset codes, as well as display up to four parameters at a time (out of about 18 to choose from), such as fuel use, engine temp, batt. voltage etc. It also has a trip computer built in. Cost is $180 US or so. It sits on the dash plugged in all the time.

    do i need to spend this $180 to fix the error code? where did you get your oxygen sensor? did you get an OEM or a universal where you have to solder the leads? thanks

    I've replaced both rear oxygen sensors on my 01. You don't need the scan tool for the repair. I would recommend you buy the OEM sensors, which are Bosch. But check www.nissanhelp.com & look for the TSB for rear oxygen sensors. I'm not sure if it applies to 2002s but if so that's probably why yours went out. The rear sensors were activating as soon as you start the car & the moisture in the exhaust was shorting them out. The TSB calls for reprogramming the ECM which turns the rear sensors on later once the moisture burns off. The ECM is covered under the longer emissions warranty (but not the O2 sensors). I replaced the sensor, then took the receipt & TSB to the dealership & they did the reprogram no charge under the emissions warranty. As far as where to buy the sensor, just google "2002 nissan pathfinder O2 sensor" & you should find a lot of places to compare prices. Good luck...

    Hello, i just went under the car and looks like i have to buy a universal 4 wire, and cut the leads and solder them and use electrical tape or shrink fit tubing to insulate... i can't reach the darn plug! it's way up in there... how the heck did you reach it?

    also, to reset the error code, can i just unplug the battery for 10 minutes after i put in the universal sensor?

    thanks!!!
  • smokey75smokey75 Posts: 434
    It's been a while since I did it but I'm pretty sure you access the plug topside. Now what is a pain is the snap in wire guides to keep the cable tucked in. Some of those are impossible to reach. The 10 min. battery disconnect should clear the codes, but don't forget about the ECM reprogram or you'll end up in the same boat again.
  • jamie29jamie29 Posts: 6
    do you think it's easier to buy a universal 4 lead sensor and just cut the leads and solder the wires underneath the car, and therefore leave in the existing cable? that way i don't have to re-route the thing? i didn't even think to look topside, i'll check that tomorrow!

    also, about the reprogramming, i have 91k miles and the dealer told me it's $330 to reprogram the thing. so, i'm thinking the old sensor lated quite a while, how long til the new one blows out?

    also my BOTH of the catalytic converters rusted out! and it's only a 2002! i cna have universals welded in a meineke for $total but the friggin' warranty should be 8 years!!!! but i got too many miles.

    you think i'm ok not to reprogram? and also, is the universal easier and just cut and solder underneath the car, and seal with shrink tubing or electrical tape?

    thanks for all your thoughts!

    The 4 wire one would probably be ok. I don't have any experience w/ other brands so hard to say. I don't blame you for not reprogramming the ECM at that price. But that seems way high. It only involves them hooking up their scan tool & updating the ECM. 1/2 hour, 1 hour labor at most.
  • jamie29jamie29 Posts: 6
    well it's only $30 more ($76 total with shipping) for the direct connect, that's what i'll do. So let me ask, the connector is the red cable at the right front side area when looking at the engine? That's the left rear one... I think what I'll do is run the new one next to the old and wire-tie it to the old one rather than the locations it's lashed to now... sound like a plan?

    i'll hook it up and do the battery disconnect for 10 mins, and then if all is well i'll pass inspection ASAP!!!

    been driving for 4 months with "rejected!" for this one reason alone. luckily no tix yet!!! LOL

    the dealer won't ECM for free due to 91k miles... it's a scam!
  • smokey75smokey75 Posts: 434
    Yeah, actually that's not a bad idea. I mean, it's kinda goofy but honestly I kinda wish I had left the other cable in place & done that & avoided the scrapes on my arms. It's pretty easy to drop the sensor through from the top. If you have other Nissan dealers I would check their prices on the ECM reprogram.

    Hello pwlong19,

    not sure if you even still own this Pathfinder, but did you ever figure out what the problem was? Just bought a used 98 Pathfinder and it's doing exactly the same thing you describe.

    Thanks,
    OK

    My sister's '02 PF with 71K miles burns a quart of oil every 1000 miles. Her dealer recomended a valve job, but I told her it would not be harm anything and to simply add a quart of oil when needed. My '01 PF has 111K miles and uses a quart every 2-3K miles. What kind of oil usage are people here with higher mileage 3.5 engines (model years 2001-2004)experiencing? Has anyone here with a 3.5 engine had their truck repaired due to oil burning? What was repaired, what was the cost, and did it resolve the issue? Thanks.

    I noticed that one of the plastic clips that holds the bottom of the front bumper cover to the frame of my truck is missing. The other clip is still there and I'm guessing the missing part is identical. It is circular in shape, and it looks like it just presses into the pre-drilled holes in the bumper cover and frame. Anyone know what this is called so I know what to ask for at the dealer's parts department? Thanks.

    I have an 02 SE and depending on my driving will go through at least a qt every 3K miles. If I just drive back and forth to work, I go through a qt. If I do extended highway driving at 70-75 mph. I can go through 2 qts. I have 120K on mine.

    I trust my mechanic and when i asked him if I should have the work done to stop the oil loss he said not to bother since body rot is the number one cause of death where I live. He said just keep feeding it oil.
