Just had the codes pulled at Autozone. It is an O2 sensor Slow response Bank 1 sensor 1, but the guy couldn't tell me which side that it is on. Can anyone tell me if this is the passenger side or drivers' side?

Thanks!

 

i have no clue but im sure if ya call the dealer tomorrow they can tell ya the dealers here are usually very cool that way

 

Bank 1 means the passenger's side (where cylinder #1 is).

Sensor 1 means the upstream sensor (before the cat).

 

Thanks Joe. This means that the new O2 sensor I installed back in June is giving the slow response. Great. I guess I'll check my connections and take it from there.
