Need Help!! code p0160

[joelala]

I have a 2001 pathfinder. Which O2 sensor is this and how do I verify that it is bad? Is it hard to change? Can I do it myself?

Any answers to my questions would be great.

Thanks

How did you get the code, because if you had it scanned I would assume it would tell you which one it is. I have a bad O2 sensor too but when i had it scanned it told me which sensor. Unfortunately i don't think i wrote down which code it was though, but i'll check right now. I'm not sure if you can do it yourself, i don't know what's involved. I'm having the guys at my dad's diesel truck change mine soon. But i also heard that you can't just change one, that you have to change them all...can anybody help me/us out with that one?

edit: i do have the code but it's not the same as yours. My code was P0158 which is bank 2 sensor 2 (at least you can eliminate that one!)

If anyone can offer me extra help with this isue, it would be much appreciated.

Go through the sticky for OBDII codes. Might help.Also try a search. Lots of info on O2 sensors. It's a common problem.

nah you dont have to replace all 4. and the scanner doesnt really tell you much that i would rely on besides the code. i had a p0160, replaced the drivers side rear o2, reset the SES light, had the ECU flashed, now its good to go.

that lists 4 diff codes for bank 2 sensor 2 but im assuming its different problems with that particular sensor....but remember mines an '02 with the vq35, but still an R50. i think thats for all R50's but correct me if im wrong.

Did you change the o2 before the converter or the o2 after the converter?

after the converter, drivers side.
