Diagnostic Procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot 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 CKP SENSOR CONNECTOR CONDITION Switch the ignition to 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 connector and/or terminals, then go to Step 13.
3		No	Go to the next step.
4	INSPECT CKP SENSOR FOR FOREIGN MATERIALS Visually inspect the CKP sensor for foreign materials. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION .) Is there any foreign materials on the CKP sensor?	Yes	Remove the foreign materials from the CKP sensor, then go to Step 13.
4		No	Go to the next step.
5	INSPECT CKP SENSOR PULSE WHEEL Visually inspect the CKP sensor pulse wheel. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION .) Are there any damage or scratches at the CKP sensor pulse wheel?	Yes	Replace the CKP sensor pulse wheel, then go to Step 13. (See CYLINDER HEAD GASKET REPLACEMENT .)
5		No	Go to the next step.
6	INSPECT CKP SENSOR Reconnect all disconnected connectors. Inspect the CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION .) Is there any malfunction?	Yes	Replace the CKP sensor, then go to Step 13. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION .)
6		No	Go to the next step.
7	INSPECT CMP SENSOR CONNECTOR CONDITION Switch the ignition to 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 connector and/or terminals, then go to Step 13.
7		No	Go to the next step.
8	INSPECT CMP SENSOR FOR FOREIGN MATERIALS Visually inspect the CMP sensor for foreign materials. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION .) Is there any foreign materials on the CMP sensor?	Yes	Remove the foreign materials from the CMP sensor, then go to Step 13.
8		No	Go to the next step.
9	INSPECT CMP SENSOR PULSE WHEEL Visually inspect the CMP sensor pulse wheel. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION .) Are there any damage or scratches at the CMP sensor pulse wheel?	Yes	Replace the CMP sensor pulse wheel, then go to Step 13. (See CYLINDER HEAD GASKET REPLACEMENT .)
9		No	Go to the next step.
10	INSPECT CMP SENSOR Reconnect all disconnected connectors. Inspect the CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION .) Is there any malfunction?	Yes	Replace the CMP sensor, then go to Step 13. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION .)
10		No	Go to the next step.
11	INSPECT PCM CONNECTOR CONDITION Switch the ignition to off. Disconnect the PCM connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 13.
11		No	Go to the next step.
12	INSPECT VALVE TIMING Inspect the valve timing. (See TIMING CHAIN REMOVAL/INSTALLATION .) Is there any malfunction?	Yes	Adjust the valve timing properly, then go to the next step. (See TIMING CHAIN REMOVAL/INSTALLATION .)
12		No	Go to the next step.
13	VERIFY DTC TROUBLESHOOTING COMPLETED Make sure to reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE .) Start the engine and warm it up completely. Perform the Pending Trouble Code Access Procedure. (See ON-BOARD DIAGNOSTIC TEST .) Is the PENDING CODE for this DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION .) Go to the next step.
13		No	Go to the next step.
14	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE .)
14		No	DTC troubleshooting completed.
