DTC DETECTION LOGIC

NOTE:
• Conditions for applying the diagnostic procedure to the stored DTCs:

The DTC is declared present when cranking the engine or at idle speed.

• If the DTC is present:

Longer starting time, requires several attempts to start the vehicle.

Diagnosis Procedure

INFOID:0000000000952664

1.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

2.

Check ground connection E17. Refer to Ground inspection in

GI-41, "Circuit Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace ground connection.

2.

CHECK CMP SENSOR

1.

Turn ignition switch OFF.

2.

Disconnect camshaft position (CMP) sensor harness connector.

3.

Turn ignition switch ON.

4.

Check the voltage between CMP sensor harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> GO TO 3.

3.

DETECT MALFUNCTIONING PART

Check the following.
• Harness connector E7, F121
• Harness for open or short between ECM and CMP sensor

>> Repair open circuit or short to ground or short to power in harness or connectors.

4.

CHECK CMP SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check the continuity between CMP sensor harness connector and ECM harness connector.

DTC No.
