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. (Initial Inspection and Diagnostic Overview.)

2. CHECK CAMSHAFT POSITION SENSOR POWER SUPPLY CIRCUIT-I

1.Disconnect camshaft position (CMP) sensor harness connector.
2.Turn ignition switch ON.
3.Check the voltage between CMP sensor harness connector and ground.





Is the inspection result normal?
YES- GO TO 8.
NO-1- P0340: GO TO 3.
NO-2- P0345: Repair open circuit, short to ground or short to power in harness or connectors.

3. CHECK CMP SENSOR POWER SUPPLY CIRCUIT-II

1.Turn ignition switch OFF.
2.Disconnect ECM harness connector.
3.Check the continuity between CMP sensor harness connector and ECM harness connector.





Is the inspection result normal?
YES- GO TO 4.
NO- Repair open circuit.

4. CHECK SENSOR POWER SUPPLY CIRCUIT

Check harness for short to power and short to ground, between the following terminals.





Is the inspection result normal?
YES- GO TO 5.
NO- Repair short to ground or short to power in harness or connectors.

5. CHECK COMPONENTS

Check the following.
- Battery current sensor (For Mexico.)
- Crankshaft position sensor (For Mexico.)
- Refrigerant pressure sensor (For Mexico.)
- EVAP control system pressure sensor (For Mexico.)
Is the inspection result normal?
YES- GO TO 6.
NO- Replace malfunctioning component.

6. CHECK APP SENSOR

For Mexico.
Is the inspection result normal?
YES- GO TO 12.
NO- GO TO 7.

7. REPLACE ACCELERATOR PEDAL ASSEMBLY

Replace accelerator pedal assembly. Without Distance Control Assist System (Without distance control assist system) or {LINK_TO_MANY:0000000007374650}{LINK_TO_MANY:0000000007374651}, "MODELS WITH
DISTANCE CONTROL ASSIST SYSTEM : Removal and Installation" (With distance control assist system).
- INSPECTION END

8. 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.





4.Also check harness for short to ground and short to power.
Is the inspection result normal?
YES- GO TO 9.
NO- Repair open circuit, short to ground or short to power in harness or connectors.

9. CHECK CMP SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

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





2.Also check harness for short to ground and short to power.
Is the inspection result normal?
YES- GO TO 10.
NO- Repair open circuit, short to ground or short to power in harness or connectors.

10. CHECK CAMSHAFT POSITION SENSOR

.
Is the inspection result normal?
YES- GO TO 11
NO- Replace malfunctioning camshaft position sensor. Exploded View.

11. CHECK CAMSHAFT (INT)

Check the following.





- Accumulation of debris to the signal plate of camshaft front end
- Chipping signal plate of camshaft front end
Is the inspection result normal?
YES- GO TO 12.
NO- Remove debris and clean the signal plate of camshaft front end or replace camshaft.

12. CHECK INTERMITTENT INCIDENT

Intermittent Incident.
- INSPECTION END


Component Inspection (Camshaft Position Sensor)


1. CHECK CAMSHAFT POSITION SENSOR-I

1.Turn ignition switch OFF.
2.Loosen the fixing bolt of the sensor.
3.Disconnect camshaft position sensor harness connector.
4.Remove the sensor.





5.Visually check the sensor for chipping.
Is the inspection result normal?
YES- GO TO 2.
NO- Replace malfunctioning camshaft position sensor.

2. CHECK CAMSHAFT POSITION SENSOR-II

Check resistance camshaft position sensor terminals as per the following.





Is the inspection result normal?
YES- INSPECTION END
NO- Replace malfunctioning camshaft position sensor. Exploded View.
