oxygen sensor 1998 chev

Feb 09, 2006 4 Replies

went to Auto Zone, had 3 codes come up. P0154 P0155 and P1153. says Bank 2 fuel control shifted lean, and a malfunction exists in the heater circuit for oxygen sensor 1 in bank 2. I crawled under to take a peek, and can find 3 sensors. How can you determine which one is bank 1 vs bank 2? I am somewhat handy and was hoping to make this repair myself. Truck does not start as ez as before the check engine light came on. Thanks!!!!

Bank 1 is the side of the engine that contains cylinder number 1. Bank 2 is the other side when there is an other side.

In your case, it would be the passenger side, sensor closest to the engine.
