Question: Why Knock Sensor Code?

What causes a knock sensor code?

This failure code can be caused by the sensor itself, the engine controller, or the wiring between the two, including the connectors. The P0325 code could also be caused by other conditions with the engine that is causing extreme knocking; however I would consider these secondary.

What happens when a knock sensor goes bad?

One symptom of a bad knock sensor is the engine doesn’t feel right while driving at speed, or while the vehicle is carrying a light or heavy load. A bad knock sensor may also not let the engine accelerate properly while driving on the highway, and cause the vehicle to lose fuel mileage.

How do I fix code P0325?

What repairs can fix the P0325 code? Replacing the ECU. Repairing or replacing the wiring harness. Replacing a faulty knock sensor. Repairing an electrical connection.

Can bad spark plugs cause knock sensor code?

Yes, if your plugs were fouled out which causes a missfire is throws the timing off. When timing is thrown off it throws knock code. Knock code sensos vibrations and if it sensos vibrations (missfiring) it retards the the timing causing a knock code. You should be fine now if you have no more codes.
