Diagnosis and repair Knock Sensor: how to fix error code P0325?
Usually, just replacing the knock sensor will solve the problem.
Before replacing any components, however, a precise diagnosis should always be made so that you don’t spend money on the wrong parts.
First, you should check all electrical connections to the sensor to see if there is breakage or corrosion.
Make sure that you check the wiring to the control unit for defects as well.
The knocking does not always have to be due to a defective sensor, often the cooling system is the trigger.
This can also possibly be remedied by checking the cooling system and the coolant temperature sensor.
A certified professional at the workshop will clear the fault codes and carry out a test drive to obtain a correct diagnosis.
