DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5 V with igni-
tion switch ON.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE-I

1.

Start engine and let it idle for at least 5 seconds.
If engine does not start, crank engine for at least 2 seconds.

2.

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Go to 

EC-430, "Diagnosis Procedure"

.

NO

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE-II

1.

Keep engine speed at more than 800 rpm for at least 5 seconds.

2.

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Go to 

EC-430, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000006037356

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 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.

DTC No.

DTC detecting condition

Possible cause 

P0340

Camshaft position sensor 
(PHASE) circuit

• The cylinder No. signal is not sent to ECM for 

the first few seconds during engine cranking.

• The cylinder No. signal is not sent to ECM 

during engine running.

• The cylinder No. signal is not in the normal 

pattern during engine running.

• Harness or connectors

(The sensor circuit is open or shorted)

• Camshaft position sensor (PHASE)
• Camshaft  (INT)
• Starter  motor
• Starting system circuit 
• Dead (Weak) battery

Is the inspection result normal?

YES

>> GO TO 3.

NO

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

3.

CHECK CMP SENSOR (PHASE) GROUND CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connectors.

3.

Check the continuity between CMP sensor (PHASE) 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 4.

NO

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

4.

CHECK CMP SENSOR (PHASE) INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1.

Check the continuity between CMP sensor (PHASE) 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 5.

NO

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

5.

CHECK CAMSHAFT POSITION SENSOR (PHASE)

Check camshaft position sensor (phase). Refer to 

EC-432, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Replace camshaft position sensor (PHASE). Refer to 

EM-53, "Exploded View"

.

6.

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 7.

NO

>> Remove debris and clean the signal plate of camshaft

rear end or replace camshaft. Refer to 

EM-53,

"Exploded View"

.

7.

CHECK INTERMITTENT INCIDENT

Check intermittent incident. Refer to 

XX-XX, "*****"

.
