Best Practices

Only use factory OEM knock sensors and be sure to check for any relevant Technical Service Bulletins (TSBs), necessary software updates, and re-calibration procedures.

Common Symptoms

When a knock sensor fails, the engine may lack power, have poor acceleration, ping or knock on acceleration, and get poor fuel economy.

The Check Engine Light may illuminate with a fault code set for one or more knock sensors.

Common Misdiagnoses

A knock sensor code isn't always triggered by a defective knock sensor. It can be triggered by a malfunctioning EGR system, a lean air-to-fuel ratio, worn ignition components, a cooling system problem, or an engine mechanical problem.
