How does the knock sensor work?

Every time the engine knock sensor notices a vibration, it sends a signal to the engine's computer, reporting how large it was. The engine's computer is programmed to expect a specified range of signals from the knock sensor. Most information from the knock sensor will be bumps in the road or closing the car door. However, when a vibration is large enough, the knock sensor signal will trigger the computer to alert the driver. This is a protective measure meant to prevent complete engine failure.

How often do knock sensors need to be replaced?

On most vehicles, the knock sensor is tough enough to last over 150,000 miles.

How are knock sensor issues diagnosed?

The check engine light and knock sensor-related OBD codes will immediately point a technician to the knock sensor. The technician will first conduct a visual inspection of the sensor and associated wiring. If the knock sensor wiring harness and electrical connectors are working properly, the technician will test the knock sensor. Further bench testing may be done. After testing is complete, the part will be replaced and the car tested to make sure the problem is resolved.

On most vehicles, the knock sensor is tough enough to last over 150,000 miles.
