Good day,
Does anyone have any info on how to reprogram the ECM to accept an aftermarket exhaust? I installed a Dynomax muffler and
3in to4in pipes, now I get a code P053 O2 sensor heat up out of range. I replaced the O2 twice and still no change.
Any help would be appreciated
Thanks, Tony
Did you reset your computer after you installed the exhaust? If not that could be your trouble. Reset it via scan tool or by unplugging the battery for a few minutes. That will reset your Computer.
