Normal Knock Sensor Signal

Abnormal Knock Sensor Signal

Diagnosis

If the PCM malfunctions in a manner which will not allow proper diagnosis of the KS circuits, DTC P0325 will set.
DTCs P0327 and P0332 diagnose the knock sensors, and related wiring. Problems encountered with the KS system should set a DTC. However, if no KS
DTC sets but the customer's complaint suggests the KS System is responsible, refer to Detonation/Spark Knock in Symptoms. See: Computers and
Control Systems/Testing and Inspection
