4		No	Go to the next step.
5	INSPECT INTAKE CAMSHAFT SPROCKET Inspect the intake camshaft sprocket. (See TIMING CHAIN REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Is there any malfunction?	Yes	Repair or replace the malfunctioning part according to the inspection results, then go to Step 16.
5		No	Go to the next step.
6	INSPECT VALVE TIMING Inspect the valve timing. (See TIMING CHAIN REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Is there any malfunction?	Yes	Adjust the valve timing properly, then go to Step 16. (See TIMING CHAIN REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
6		No	Go to the next step.
7	INSPECT CKP SENSOR CONNECTOR CONDITION Switch the ignition 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 16.
7		No	Go to the next step.
8	INSPECT CKP SENSOR FOR FOREIGN MATTER Visually inspect the CKP sensor for foreign matter. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Is there any foreign matter on the CKP sensor?	Yes	Remove the foreign matter from the CKP sensor, then go to Step 16.
8		No	Go to the next step.
9	INSPECT CKP SENSOR PULSE WHEEL Visually inspect the CKP sensor pulse wheel. Is there any damage or scratching on the CKP sensor pulse wheel?	Yes	Replace the CKP sensor pulse wheel, then go to Step 16.
9		No	Go to the next step.
10	INSPECT CKP SENSOR Reconnect all disconnected connectors. Inspect the CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Is there any malfunction?	Yes	Replace the CKP sensor, then go to Step 16. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
10		No	Go to the next step.
11	INSPECT INTAKE CMP SENSOR CONNECTOR CONDITION Switch the ignition off. Disconnect the intake 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 16.
11		No	Go to the next step.
12	INSPECT INTAKE CMP SENSOR FOR FOREIGN MATTER Visually inspect the intake CMP sensor for foreign matter. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Is there any foreign matter on the intake CMP sensor?	Yes	Remove the foreign matter from the intake CMP sensor, then go to Step 16.
12		No	Go to the next step.
13	INSPECT INTAKE CMP SENSOR PULSE WHEEL Visually inspect the intake CMP sensor pulse wheel. Is there any damage or scratching on the intake CMP sensor pulse wheel?	Yes	Replace the intake CMP sensor pulse wheel, then go to Step 16.
13		No	Go to the next step.
14	INSPECT INTAKE CMP SENSOR Reconnect all disconnected connectors. Inspect the intake CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Is there any malfunction?	Yes	Replace the intake CMP sensor, then go to Step 16. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
14		No	Go to the next step.
15	INSPECT PCM CONNECTOR CONDITION Switch the ignition 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 the next step.
15		No	Go to the next step.
16	VERIFY DTC TROUBLESHOOTING COMPLETED Always reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) Start the engine and warm it up completely. Perform the Pending Trouble Code Access Procedure. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) 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 [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Go to the next step.
16		No	Go to the next step.
17	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .)
17		No	DTC troubleshooting completed.
