Common Sensor Faults.



A: Antifreeze Contamination

Antifreeze in the exhaust will attack and destroy the sensing element. A leaking head gasket commonly causes antifreeze contamination.


B: Rich Fuel Mixture

This will cause a heavy black carbon layer to form on the sensor element. Rich fuel mixture is usually caused by a failure in the air/fuel metering system


C: High Oil Consumption

This will coat the sensing element with a crusty, brown layer. Worn piston rings and valve guides, or other internal engine problems can cause high oil consumption.


D: Silicone Poisoning

Residue from silicone lubricants will rapidly destroy the sensors element. Care should be exercised not to get silicone lubricants on the oxygen sensor when it is being installed.
