Ive looked up the code and its bank 2 sensor 1 insufficient switching or something. Ive taken it to auto zone who said i need new o2 sensor, advanced said i need a new MAF (wtf) and a mechanic told me i need a new o2 on the passenger side infront of cat. My question, do i just need to replace the o2 sensor or what? Thanks

 

cmon guys, 3 days being posted and nothing?

 

It's going to be on drivers side exhaust closet to the manifold I would say just replace it yourself you have to warm up the engine for little so you don't strip the thread on oxygen sensor when your removing it. If it had a bad maf it would have given you a code for a bad maf...you can clean the maf yourself theres a article on that. You can also check out the wiring to the oxygen sensor to make sure its not burnt or cut..

 

this morning i was driving to school and the cel went off, im going to have it scanned for codes again and see if anything comes up. will report back..
