What happens if the O2 sensor heater fails?
The O2 sensor heater circuit is used to heat the internal parts of the O2 sensor to help it start give feedback to the ECM quicker. If the heater fails, the O2 sensor may still give feedback to the ECM but will take more than the normal time of less than two minutes. Need help with a P0135 code?
