Nissan Maxima Service and Repair Manual: P0327, P0328, P0332, P0333 KS
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 ECM.

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conducting the next test.
- Turn ignition switch OFF and wait at least 10 seconds.
- Turn ignition switch ON.
- Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION: Before performing the following procedure, confirm that battery voltage is more than 10 V at idle.
2.PERFORM DTC CONFIRMATION PROCEDURE
- Start engine and run it for at least 5 seconds at idle speed.
- Check 1st trip DTC.
Diagnosis Procedure
1.CHECK GROUND CONNECTION
- Turn ignition switch OFF.
- Check ground connection E9.
2.CHECK KNOCK SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
- Disconnect knock sensor harness connector and ECM harness connector.
