Major sensor problems w/ 01 pathfinder

[jclaxcoach]

ses went on and This all started when i took it to a shop that told me bank 1 o2 sensor and replaced it only to have the light come up again......... so in it went to nissan where i got a cam pos sensor and was told it needed a mafs if the light went back on. now i have done all that and the light is back on and this is getting expensive. just thought that there may be a reason everything is going or if there is something that is tripping all the sensors????? I am out of ideas so thats why i'm going to the big computer at nissan dealer. any help would be useful. advice was to get code from autozone.

OK I took your advice and went to autozone. P0158 bank 2 sensor O2 sensor high volts ....... and..... P0160 O2 sensor CKT no activity bank 2 sensor 2. I'm not sure what this all means or if the hand held diagnostic is giving a false reading but i'm beginning to think that i am the most unlucky sensor failing nissan owner on the planet. What is the real problem? If you can help please let me know.bill

I think I am the first to figure this problem out. About 1.5 years ago I ran into funny problem codes and this same stalling problem. I took it in 3 times to the same Nissan Dealership and they couldnt' figure it out. They kept giving me new "fixes" to try. I finally took it to an independent repair place and the guy figured it out. The Turbine Revolution Sensor on top of your Transmission is probably faulty and is leaking transmission fluid through it. Because of this leak, you will probably get funny problem codes down the road here. The transmission fluid flowd down the wiring harness of this sensor into a whole host of other harnesses, triggering Intake sensor issues, O2 sensor issues, etc. The stalling is due to the low transmission fluid. Check your transmission fluid. If it's low, then fill it up. Your problem should go away. Good luck. Let me know if this fixes the problem. BTW, the metal housing blocks the visibility of the transmission fluid on the ground until the leak gets severe, like mine did. Good luck and please repost to let me know.
