Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Oxygen Sensor
Oxygen sensor(s) is threaded into exhaust manifold(s). Turn ignition off. Connect test harness between ECM and vehicle wire harness. Connect voltmeter between terminals specified in the OXYGEN SENSOR TEST TERMINALS table. Turn ignition on. If voltmeter does not indicate .4 - .5 volt when ignition is first turned on, and less than .1 volt in less than 2 minutes, check wiring between ECM and oxygen sensor. If wiring is okay, replace oxygen sensor.
