The knock sensor is located on the right side of engine block, to the rear of right engine mount.
P0325-KNOCK SENSOR 1 CIRCUIT
This monitor runs above 2000 rpm, under open throttle conditions. The Knock diagnostic does not run at idle or during decelerations. The high voltage test runs all the times the engine is running.
The PCM detects the Knock Sensor voltage out of limits. Two Trip Fault. Three good trips to turn off the MIL.
