Which side is bank 1? My SES light has been on for a while, so I took it to autozone to see waht the code was and the guy said it was an O2 sensor on bank 1. Just wondering which side is bank 1 so I replace the correct one!

Thanks,
Chad

Your car has 4 O2 sensors. Two on Bank 1 and two on Bank 2.

You will need to find out which sensor on Bank 1 is throwing the code. B1S1 (bank 1 sensor 1) would be the pre-cat sensor on the drivers side. B1S2 (bank 1 sensor 2) would be the post-cat sensor on the drivers side.

he did say it was the front one, and he even pointed to the drivers side one, he just wans't sure which side was bank 1 or bank 2.

O2 sensors very expensive?

Thanks for the fast replys guys

Before buying anything post the actual code (have it read again if he didn't give it to you) - if he didn't know the difference between B1 and B2, might not know the difference between S1 and S2 either.

As for price, around 45 bucks if I'm not mistaken

If you just buy one off a parts counter it'll probably be close to twice that price, and even more from the dealer. Better deals could probably be found online though.
