Oxygen sensor
 

I have a 2001 galant gtz.. My check engine light came on so we scanned it with a scanner.. It threw out the code bank sensor #2.. Dont really know which oxygen sensor that is.. I checked napa and auto zone but they give so many.. I would prefer the O.E.M part.. Can Anyone help???

need to know more.
you have 4 oxygen sensors on your car, and the code will tell you which one it sees as a problem.
You need to tell us if its bank 1 or 2, and then sensor 1 or 2.

Hmmm... I guess ill have to call my friend who scanned it because all he told me was bank sensor #2... Im almost positive he said it was the one in back if that helps any... Sorry i dont know too much about sensors, ill try to find out.. Thanks
