Possible causes

– Faulty knock sensor
– Knock sensor circuit poor electrical connection
– Knock sensor harness is open or shorted
– Faulty Engine Control Module (ECM)

P0328 Description

The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Engine Control Module (ECM).
