DTC P0345 [AJ] DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record FREEZE FRAME DATA on repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Check for related Service Bulletins and/or on-line repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY RELATED PENDING CODE OR STORED DTC Turn the ignition switch off, then to the ON position (Engine off). Verify the related PENDING CODE or stored DTCs. Is the DTC P0340 also present?	Yes	Go to the DTC P0340 inspection. (See DTC P0340 ). If the DTC P0340 dose not stored, go to the next step.
3		No	Go to the next step.
4	VERIFY CMP SENSOR (LH) VOLTAGE Disconnect CMP sensor (LH) connector. Connect voltmeter between CMP sensor (LH) connector terminals A and B. Check the voltage in AC range when cranking the engine. Is there a voltage reading?	Yes	Go to the next step.
4		No	Go to step 10.
5	VERIFY CMP SENSOR (LH) RESISTANCE Measure CMP sensor (LH) resistance. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION ). Is resistance normal?	Yes	Check CMP sensor (LH) pulse wheel for damage. If there is any malfunction, replace CMP sensor (LH) pulse wheel and go to Step 13. (See TIMING CHAIN REMOVAL/INSTALLATION ).
5		No	If resistance is 0 ohm , then go to the next step. If resistance is infinity, then go to Step 8.
6	INSPECT CMP SENSOR (LH) CIRCUIT FOR SHORT TO GROUND Turn the ignition switch off. Check continuity between the following circuits: CMP sensor (LH) terminal A and body ground CMP sensor (LH) terminal B and body ground Is there continuity?	Yes	Repair or replace harness for short to ground, then go to Step 13.
6		No	Go to the next step.
7	INSPECT CMP SENSOR (LH) CIRCUIT FOR SHORT WITH EACH OTHER Turn the ignition switch off. Disconnect CMP sensor (LH) connector. Check continuity between CMP sensor (LH) terminal A and B. Is there continuity?	Yes	Repair or replace harness for short with each other, then go to Step 13.
7		No	Go to the next step.
8	INSPECT PCM CONNECTOR FOR POOR CONNECTION Turn the ignition switch off. Disconnect PCM connector. Check for poor connection (such as damaged, pulled-out pins, and corrosion). Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 13.
8		No	Go to the next step.
9	INSPECT CMP SENSOR (LH) CIRCUIT FOR OPEN CIRCUIT Turn the ignition switch off. Check continuity between the following circuits: CMP sensor (LH) terminal A and PCM terminal 2AA CMP sensor (LH) terminal B and PCM terminal 2AB Is there continuity?	Yes	Go to the next step.
9		No	Repair or replace harness for open circuit, then go to Step 13.
10	INSPECT CMP SENSOR (LH) Inspect CMP sensor (LH). (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION ). Is there any malfunction?	Yes	Replace CMP sensor (LH), then go to Step 13. See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION ).
10		No	Go to the next step.
11	INSPECT STOPPER PIN MECHANISM Remove timing chain. Inspect stopper pin. (See VARIABLE VALVE TIMING ACTUATOR INSPECTION ). Is stopper pin mechanism normal?	Yes	Go to the next step.
11		No	Replace variable valve timing actuator (LH), then go to Step 13. (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION ).
12	INSPECT ROTOR POSITION Remove variable valve timing actuator (LH). (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION ). Is rotor position at maximum valve timing retard?	Yes	VARIABLE VALVE TIMING MECHANISM IS NORMAL NOTE: This DTC is detected by intermittent concern. Intermittent concern might be removed by cleaning mode of variable valve timing control function. Go to the next step.
12		No	Replace variable valve timing actuator, go to the next step. (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION ).
13	VERIFY TROUBLESHOOTING OF DTC P0345 COMPLETED Make sure to reconnect all disconnected connectors. Turn the ignition switch to the ON position. Clear the DTC from the PCM memory using the WDS or equivalent. Start engine. Access MAF PID using the WDS or equivalent. NOTE: MAF PID should indicate 1.95 g/s {0.268 lb/min} or above during this test Is same DTC present?	Yes	Replace PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION ).
13		No	Go to the next step.
14	VERIFY AFTER REPAIR PROCEDURE Perform "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE ). Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE ).
14		No	Troubleshooting completed.
