>> Check starting system.

2.

CHECK GROUND CONNECTION

1. Turn ignition switch OFF.

DTC No.

Trouble diagnosis content

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

(Camshaft position sensor circuit is open or shorted)

• Camshaft position sensor
• Intake camshaft
• Starter motor
• Starting system circuit 
• Dead (Weak) battery

YES

>> GO TO 3.

NO

>> Repair or replace ground connection.

3.

CHECK CAMSHAFT POSITION SENSOR (PHASE) POWER SUPPLY CIRCUIT

1. Disconnect camshaft position sensor (PHASE) harness connector.

2. Turn ignition switch ON.

3. Check the voltage between camshaft position 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 CAMSHAFT POSITION SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connectors.

3. Check the continuity between camshaft position 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 5.

NO

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

5.

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

1. Check the continuity between camshaft position 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 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 

EC-281, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 7.
