I got the P0155 code and that is for the right bank pre-cat sensor, I am just not sure which is the right bank sensor? Any help please!!!!

 

Bank 1 = drivers side = Cyls 1/3/5/7

Bank 2 = passenger side - Cyls 2/4/6/8

Generally, left and right is determined as viewed from the drivers seat, so you are looking at the right/passenger side.

The code definitions only reference Bank 1 or Bank 2, not left or right.

 

Thanks for the help. In the haynes manual it states right bank for the PO155, I just didn't know which side was considered right. You set me strait.

 

Use Shoebox's LT1-specific code list, not Haynes, etc. The OBD-II codes are on a "tab" at the bottom of the page:

Thanks for the info. Injuneer! I never realized shoebox had OBD2 codes @ the bottom.
