Diagnosis

If the PCM malfunctions in a manner which will not allow proper diagnosis of the knock sensor system, DTC P0325 will set.

DTCs P0327 and P0332 are designed to diagnose the knock sensors, and related wiring. Problems encountered with the KS system should set a DTC. However, if the customer's complaint is detonation/spark knock, use the tables for DTC P0327 or P0332 to diagnose the condition.
