Hey everybody,

Just had Autozone pull the code for my service engine soon light. They said it was a bad o2 sensor in bank 1. I didn't get the exact code number. I bought a new sensor, but I'm not sure which one to replace. Does anyone know what 'bank 1' refers to? They said it was closest to the manifold, so that narrows it down to 2. Any info appreciated. Thanks.

 

change one of them un plug the batt for 10 mins to clear the code and see if it comes on. if it does its the other if it dosent than its gravy

 

bank one is the side with the #1 cylinder, bank 2 is the opposite side
