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.

  1. Turn ignition switch OFF and wait at least 10 seconds.
  2. Turn ignition switch ON.
  3. 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

  1. Start engine and run it for at least 5 seconds at idle speed.
  2. Check 1st trip DTC.

Diagnosis Procedure

1.CHECK GROUND CONNECTION

  1. Turn ignition switch OFF.
  2. Check ground connection E9.

2.CHECK KNOCK SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

  1. Disconnect knock sensor harness connector and ECM harness connector.
  2. Check the continuity between knock sensor harness connector and ECM harness connector
  3. Also check harness for short to ground and short to power.
