Diagnosis
If the PCM malfunctions in a manner which will not allow proper diagnosis of the
KS circuits, DTC P0325 will set.
DTC P0327 is designed to diagnose the
knock sensors, and related wiring. Problems encountered with the
KS system should set a DTC. However, refer to Detonation/Spark Knock in Symptoms if no DTC sets, and the customers complaint of detonation points to the KS system.
