How Much Does a Knock Sensor Replacement Cost?

Knock Sensor Replacement Service and Cost

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.

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 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.
