DTC P0016 DIAGNOSTIC PROCEDURE TABLE

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 the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify 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	INSPECT CMP SENSOR CONNECTOR FOR POOR CONNECTION Turn the ignition switch off. Disconnect the CMP sensor connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 13.
3		No	Go to the next step.
4	INSPECT CMP SENSOR FOR FOREIGN MATERIAL Remove the CMP sensor. Inspect the CMP sensor for foreign materials. Is there any foreign material on the CMP sensor?	Yes	Remove foreign material from the CMP sensor, then go to Step 13.
4		No	Go to the next step.
5	INSPECT CMP SENSOR PULSE WHEEL Visually inspect the CMP sensor pulse wheel. Are there any damage or scratches at the CMP sensor pulse wheel?	Yes	Replace the camshaft, then go to Step 13. (See CYLINDER HEAD GASKET REPLACEMENT .)
5		No	Go to the next step.
6	INSPECT CMP SENSOR Inspect the CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION .) Is the CMP sensor normal?	Yes	Go to the next step.
6		No	Replace the CMP, then go to Step 13.
7	INSPECT CKP SENSOR CONNECTOR FOR POOR CONNECTION Turn the ignition switch off. Disconnect the CKP sensor connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 13.
7		No	Go to the next step.
8	INSPECT CKP SENSOR FOR FOREIGN MATERIAL Remove the CKP sensor. Inspect the CKP sensor for foreign material. Is there any foreign material on the CKP sensor?	Yes	Remove foreign material from the CKP sensor, then go to Step 13.
8		No	Go to the next step.
9	INSPECT CKP SENSOR PULSE WHEEL Visually inspect the CKP sensor pulse wheel. Are there any damage or scratches on the CKP sensor pulse wheel?	Yes	Replace the CKP sensor pulse wheel, then go to Step 13. (See TIMING CHAIN REMOVAL/INSTALLATION .)
9		No	Go to the next step.
10	INSPECT CKP SENSOR Inspect the CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION .) Is the CKP sensor normal?	Yes	Go to the next step.
10		No	Replace the CKP sensor, then go to Step 13. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION .)
11	INSPECT PCM CONNECTOR FOR POOR CONNECTION Turn the ignition switch off. Disconnect the PCM sensor connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 13.
11		No	Go to the next step.
12	INSPECT VALVE TIMING Inspect valve timing. (See TIMING CHAIN REMOVAL/INSTALLATION .) Is valve timing normal?	Yes	Go to the next step.
12		No	Adjust the valve timing properly, then go to the next step. (See TIMING CHAIN REMOVAL/INSTALLATION .)
13	VERIFY TROUBLESHOOTING OF DTC P0016 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 the engine and run it at the idle. Retrieve the DTC using the WDS or equivalent. Is the PENDING CODE for this 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 .) Is there any DTC present?	Yes	Go to applicable DTC inspection. (See DTC TABLE .)
14		No	Troubleshooting completed.
