2002 Mustang GT DTC Error Codes. Help?
I am experiencing a total of 8 error codes on my Mustang's computer. The codes read:
P0135 - O2 Sensor Heater Circuit
P0136 - O2 Sensor Circuit
P0141 - O2 Sensor Heater Circuit
P0155 - O2 Sensor Heater Circuit
P0156 - O2 Sensor Circuit
P0161 - O2 Sensor Heater Circuit
P0443 - Evaporative Emission System Purge Control Valve A Circuit
P1451 - Evaporative Emission System Vent Control Circuit
I do not have catalytic converters so I know this can be provoking the issue. These codes appeared as soon as I replaced my off-road X-pipe with another off-road X-pipe. I had to do this because the first X-pipe was crunched against the frame when bottoming out in a steep driveway. It was night time and I had poor judgement. That is besides the point. Anyways, I had a pair of MIL eliminators on the first X-pipe, but was unsuccessfully able to remove them. Of course these eliminators worked just fine. I then purchased another pair of MIL eliminators. These, however, did not work. All four O2 sensors have been replaced within the past year. I decided to purchase a tuner with Bama tunes in hopes that most or some of these codes would disappear. I do not feel that this is the case anymore. Since I live in Ohio, I am required to have my vehicle emissions-tested every two years. Until I can get these codes to disappear, I cannot renew my vehicle's registration. I cleared the codes and set my Mustang back to its stock tune right before testing it at a self-serve testing kiosk. Apparently, clearing codes and resetting the computer disables readiness sensors. The kiosk read that only 3 out of the 8 available readiness sensors were sending signals to the testing unit. Because of this, I am required to have a tailpipe test which basically sniffs the exhaust fumes. I will fail this instantaneously. How can I fix/remove these error codes?
