About Knock Sensor

The knock sensor is a component that tells the PCM when an engine knock has occurred. This is all taken care of by the PCM which uses the data to resolve the ignition progression.

Knock sensor operation

The knock sensor is able to sense unusual motions, that lets the engine know if everything is good. A light may appear while driving due to a knock in the engine. And once the PCM realizes that the sensor is not working, then the car may lose engine efficiency.

Common issues with a bad knock sensor

A bad knock sensor can lead to a lot of problems like loud sounds, poor fuel economy, and bad engine performance.
