OBD-II Trouble Code P0325 – Knock Sensor Circuit Malfunction

Knock Sensor Circuit Malfunction

Description:
Each knock sensor is fitted to the right bank and left bank of the cylinder block to detect engine knocking. This sensor contains a piezoelectric element which generates a voltage when it becomes deformed, which occurs when the cylinder block vibrates due to the knocking. If engine knocking occurs, ignition timing is retarded to suppress it.

Possible Causes:
A code P0325 most likely means one or more of the following has happened:
> The knock sensor is faulty and needs to be replaced
> There is a wiring short/fault in the knock sensor circuit Possible Solutions

Possible Solutions:
> Check the resistance of the knock sensor
> Check for broken/frayed wires leading to the sensor
> Replace the knock sensor
