Knock Sensor Replacement

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.

How is a knock sensor replaced?

If the knock sensor is faulty, the technician will unscrew the bad sensor and install a new one. There is normally only one electrical connector per knock sensor, and there may be more than one knock sensor on the engine.

Can I replace the knock sensor myself?

Most people can replace a knock sensor, and very few basic tools are needed — but diagnostics can be tricky. It's vital that the sensor is diagnosed correctly. If diagnosing the switch proves difficult or impossible, the best idea is to contact a professional.
