well my light just came on and i had the comp read and it said my system was to lean and that there was something with a bank 2....so i know that there is possibly a problem with the 02 sensor but what is the bank 2?
Did you install after market off road X-pipe or H-pipe? If my memory serves me correct the BANK 2 should be a rear 02 sensor circuit fault for the rear cats? If you have a aftermarket programmer (Diablo Predator, SCT X-caliber) you can turn it off since you don't need that sensor anymore. Are you using "MIL Eliminators"? Even with a catted X-pipe or H-pipe you can still get this code. You should also check the wiring from the 02 sensor to the PCM to make sure that there are no corroded or broken wires.
well i took the steeda spacer off and drove it around and the light went off....i guess im just gonna work on it a little if that doesnt work then send the damn thing back
