Hi All, As I understand things to work, the O2 Pre-Heat should clear from the ECU once I have a cold start. For some reason this is not happening and I continue to see that the Pre-Heat is monitor shows incomplete? I recently had my ECU's re-flashed in the hopes that my O2 Pre-Heat, O2, and EVAP would reset and be able to be ready for an emissions test. I have also done 500 miles of Ferrari drive cycles with the car. Any thoughts, ideas, I would be grateful
O2 sensor preheat is an easy monitor to set. If it does not set, check the fuse that supplies the power to the O2 sensor. Otherwise, you have to ask the person who did the re-flash.
Yes, O2 sensor is the name of the fuse which feeds power to the O2 sensor to heat up the O2 sensor to operating temperature.
