New Oxygen Sensor Not Working. Oxygen sensor failure can often be traced to one of three common factors: Sometimes, oxygen detector devices get clogged and contaminated due to the byproducts of the fuel. You should refer to the vehicle’s wiring schematic. Multiple reasons can cause the oxygen detector device to fail. If the light comes on with the ignition switch off or when the key only is turned on (engine off), then there’s a problem with the heater circuit. If the o2 sensor has been changed, the sensor needs to be reset, and can be done in several ways like disconnecting the o2 sensor to force the pcm to relearn the. Age and high mileage, an internal contaminant (poisoning) or an electrical issue. One or two wire unheated oxygen sensors. A defective oxygen sensor may not trigger a check engine light, but it can still cause your fuel mileage to go down.
