I got this code pulled from auto zone yesterday bc my ses light was on and i think this is an o2 sensor problem i was just wondering if the maxima has 2 of them by the way i have a 2001 maxima se. Thanks in advance...

Dunno if codes from diff manufactures are the same.. but 0171 for ford Zetec is MAF all the way. And if you tell me you have an aftermarket cone filter great chances it is your maf.

just wait for another reply.

Autozone often pulls only 1 code when there are multiple. I bet you also have P0174 which is the other bank running lean. MAF is really the only problem that causes both sides to run lean. If in fact you have only 1 code (needs to be tested with ODB II), then start looking at O2 sensors or exhaust leaks. The possibility of both O2 sensors being out or both ehaust pipes having a leak is slim. I replaced my MAF last week when I realized I had both codes.

The MAF problem is common. I will never buy nissan again!
Toyota's are way better and are more dependable. since i bought the nissan i have spent around $2000 just on electronic stuff such as O2 sensors, Maf, Coils, Plugs etc. waiting for more stuf to go bad. i never had any problem with my 01 camry.
