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.
>>
GO TO 2.
PERFORM DTC CONFIRMATION PROCEDURE
-
Start engine and run it for at least 5 seconds at idle speed.
-
Check 1st trip DTC.
Is 1st trip DTC detected?
YES>>Proceed to Diagnosis Procedure.
NO>>To check malfunction symptom before repair: Refer to Intermittent Incident.
NO>>Confirmation after repair: INSPECTION END
CHECK KNOCK SENSOR GROUND CIRCUIT
-
Disconnect knock sensor harness connector and ECM harness connector.
-
Check the continuity between knock sensor harness connector and ECM harness connector.

Also check harness for short to ground and short to power.
Is the inspection result normal?
YES>>GO TO 2.
NO>>Repair open circuit, short to ground or short to power in harness or connectors.
CHECK KNOCK SENSOR INPUT SIGNAL CIRCUIT
-
Check the continuity between knock sensor harness connector and ECM harness connector.

Also check harness for short to ground and short to power.
Is the inspection result normal?
YES>>GO TO 3.
NO>>Repair open circuit, short to ground or short to power in harness or connectors.
CHECK KNOCK SENSOR
Check knock sensor. Refer to Component Inspection.
Is the inspection result normal?
YES>>INSPECTION END
NO>>Replace malfunctioning knock sensor. Refer to Exploded View.
CHECK KNOCK SENSOR
-
Turn ignition switch OFF.
-
Disconnect knock sensor harness connector.
-
Check resistance between knock sensor terminal as per the following.
NOTE:
It is necessary to use an ohmmeter which can measure more than 10 MΩ.
Knock sensor Resistance + - Terminals 1 2 Approx. 532 - 588 kΩ [at 20°C (68°F)] CAUTION:
Never use any knock sensors that have been dropped or physically damaged. Use only new ones.
Is the inspection result normal?
YES>>INSPECTION END
NO>>Replace malfunctioning knock sensor. Refer to Exploded View.
