WebBecause this is an effect on the sensor electronics, it varies slightly from sensor to sensor. The net effect of the ideal gas law (-0.07%) and the sensor electronics (+0.10%) is an increase in the output of the sensor by 0.03% per ºC increase in temperature in dry air. For example, if an O2 sensor were calibrated to read 20.95% Webwhen the engine is in closed loop. While in closed loop the O2 sensor is the primary sensor for air/fuel mixture control. Since the O2 sensor's only job is to monitor oxygen in the exhaust, any air flowing past it from the air injection would cause the O2 sensor to give a false lean signal. The PCM would richen the mixture in response to it.
