02 senson

Be careful with this diagnostic approach, a fault code is just a piece of information used to help you diagnose the problem, and replacing a part without a proper diagnosis is asking for trouble. If you post the code, we can provide some info that may help avoid replacing unneeded parts. If you do replace the part, I suggest using only OE parts. O2 sensors are tuned specifically for each engine, so using any aftermarket sensors may cause the check engine light to come on again.
