2002 Trans Am with O2 problems
2002 Trans Am with O2 problems
I have a 2002 trans am and using a predator U7198 (9r15). Lately I have been having the same trouble code of P0155 popping up and it will not go away. I have a set of long tube headers with the front O2 sensors connected and I have O2 simulators in the rear due to the "off-road" set up. Is there any way I can just "tune out" the O2 sensors completely? I have attached the original backup and the last written tune. Any help will be greatly appreciated, thanks.

RE: 2002 Trans Am with O2 problems
hmmm.. that code is for the O2 sensor for bank 2 sensor 1 - which is the front O2 sensor on the passenger side of the car...
it's for the heater circuit....
did you have to use wire harness extensions for the O2 sensors with the LT headers?

The O2 sensor does have a harness extension, it recently started to have this problem. Do you think it could be the actual sensor or is there a way to check if it is something else? What else can it be?
