Common Symptoms

A failed oxygen sensor may cause the vehicle to fail an emissions test. The failed sensor will cause a trouble code to be set and the Check Engine Light to illuminate.

Oxygen sensors can fail if they are contaminated with oil, coolant, or silicone. If fluid contamination has caused an oxygen sensor failure, the source of the fluid must be resolved or the new sensor may be ruined.

Common Misdiagnoses

Intake and exhaust leaks can trigger an oxygen sensor trouble code, but the oxygen sensor does not require repair. Repairing the leak will resolve the problem.

On vehicles 1996 and newer, using an inexpensive "universal" oxygen sensor will cause problems with the emissions system and is highly discouraged.

It is common for rear oxygen sensors to be incorrectly replaced when addressing problems with the catalytic converters.
