Hello guys, would appreciate your comments. I get error codes P2234 and P1140, the OBDeleven code reader tells me they are the O2 sensors on bank 2, up and downstream. Fine but which one is bank 1 and which one is bank 2 when you are in front of the car looking at the engine in front of you? would hate to replace the good O2 sensors. Thank you

George

Bank 2 is the right hand side as you look at the engine from the front of the car.

Thank you James, that is what I thought too but was not 100%
