Where are the knock sensors located?
The knock sensor is located on the outside of the engine block. It is intended to record knocking noise in all engine operating states in order to prevent engine damage. The knock sensor “listens out for” the structure-borne vibrations from the engine block and converts these into electrical voltage signals.
Is knock sensor code serious?
How serious is the P0325 code? P0325 is generally not a serious code and should be able to be driven without issue to a safe location once the malfunction occurs. Some vehicles may experience a slight lack of engine power as the ECU will retard timing to prevent damage in case the engine was knocking.
