Diagnosis Procedure

  1. CHECK STARTING SYSTEM

    Turn ignition switch to START position.

    Does the engine turn over? Does the starter motor operate?

    YES: GO TO 2.

    NO: Check starting system.

  2. CHECK GROUND CONNECTION
    1. Turn ignition switch OFF.
    2. Check ground connection E21. Refer to Ground Inspection in "CIRCUIT INSPECTION ".

    Is the inspection result normal?

    YES: GO TO 3.

    NO: Repair or replace ground connection.

  3. CHECK CAMSHAFT POSITION (CMP) SENSOR (PHASE) POWER SUPPLY CIRCUIT
    1. Disconnect camshaft position (CMP) sensor (PHASE) harness connector.
    2. Turn ignition switch ON.
    3. Check the voltage between CMP sensor (PHASE) harness connector and ground.

    Is the inspection result normal?

    YES: GO TO 4.

    NO: Repair open circuit or short to ground or short to power in harness or connectors.

  4. CHECK CMP SENSOR (PHASE) GROUND CIRCUIT FOR OPEN AND SHORT
    1. Turn ignition switch OFF.
    2. Check the continuity between CMP sensor (PHASE) harness connector and ECM harness connector.

    3. Also check harness for short to power.

    Is the inspection result normal?

    YES: GO TO 5.

    NO: Repair open circuit or short to ground or short to power in harness or connectors.

  5. CHECK CMP SENSOR (PHASE) INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
    1. Disconnect ECM harness connector.
    2. Check the continuity between CMP sensor (PHASE) harness connector and ECM harness connector.

    3. Also check harness for short to ground and short to power.

    Is the inspection result normal?

    YES: GO TO 6.

    NO: Repair open circuit or short to ground or short to power in harness or connectors.

  6. CHECK CAMSHAFT POSITION SENSOR (PHASE)

    Refer to "COMPONENT INSPECTION ".

    Is the inspection result normal?

    YES: GO TO 7.

    NO: Replace camshaft position sensor (PHASE).

  7. CHECK CAMSHAFT (INT)

    Check the following.

    • Accumulation of debris to the signal plate of camshaft (1) rear end
    • Chipping signal plate of camshaft rear end

    Is the inspection result normal?

    YES: GO TO 8.

    NO: Remove debris and clean the signal plate of camshaft rear end or replace camshaft.
