DTC P0325 - Knock Sensor

  1. Perform PCM reset procedure. See PCM RESET PROCEDURE/CLEARING CODES  . Start engine. Raise and hold engine speed at 3000 RPM with transmission in Park or Neutral until radiator fan comes on. Let engine idle. Raise and hold engine speed at 3000-4000 RPM with transmission in Park or Neutral for at least 10 seconds.
  2. If DTC P0325 is not indicated, system is functioning properly at this time. Failure is intermittent (test drive may be necessary). Check for poor connections or loose wires at KS and PCM connectors. See WIRING DIAGRAMS  section. Repair as necessary. If DTC P0325 is indicated, go to next step.
  3. Turn ignition off. Disconnect KS connector. Check for continuity between ground and PCM connector terminal D6. See Figure . If continuity exists, repair short in Red/Blue wire between PCM and KS. See WIRING DIAGRAMS  section. If continuity does not exist, check continuity of Red/Blue wire between PCM and KS.
  4. If continuity does not exist, repair open in Red/Blue wire between PCM and KS. If continuity exists, substitute a known good KS and recheck. If DTC P0325 is not indicated, replace original KS. If DTC P0325 is indicated, substitute a known-good PCM and recheck for symptom or DTC.
