well i went to autozone and had them pull the codes from my car and it said that the bank 1 sersor 2 was bad? witch one would that be? thanks for the help.

 

the back one i believe.

 

I would agree with ^ him. Rear sensor.

 

what is the deal with the sensors in our cars ? dont you guys think its alittle to early for us to be having sensor problems all the time ?

i might as well go out and get a few dozen of them now to save me some hassel .

 

well i was told both the front and the rear are $250+ so it sux.

 

It's emissions related so if you haven't modified anything on your car that's fuel/air related, it should be covered under warranty for 2 years minimum. If it's been taken out, put back in, taken out and chewed on by a pack of rabid pit bulls and crossthreaded on the way back in.... you may have some difficulty convincing them to do it. Haven't done any mods at all? Should be covered by the federal protection plan on emissions equipment. I just found out the federal regulations changed, so here's a link:

ya ive got a catback would the rear sensor make me have bad mpg? cause my mpg suck ***.

 

yes it can

 

yay, i guess i get to ask the dealer to cover it lol

 

Cross your fingers just in case. Good luck!

 

thats a good thing to know I get a cel that says something like no o2 sensor activity on bank 1 so it is the rear o2 sensor which means I can just get under there and replace it with no problem.

 

bank1 sensor what? banks are right and left (since we are i4's we only have bank1) sensor 1 and 2 are front and rear
