2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT INTAKE CMP SENSOR CONNECTOR CONDITION • Switch the ignition to 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 14.
3		No	Go to the next step.
4	INSPECT INTAKE CMP SENSOR POWER SUPPLY CIRCUIT FOR SHORT TO GROUND OR OPEN CIRCUIT • Verify that the intake CMP sensor connector is disconnected. • Switch the ignition to ON (engine off). • Measure the voltage at the intake CMP sensor terminal C (wiring harness-side). • Is the voltage B+?	Yes	Go to the next step.
4		No	Inspect the ENG BAR 15 A fuse. • If the fuse is blown: ― Repair or replace the wiring harness for a possible short to ground. ― Replace the fuse. • If the fuse is deteriorated: ― Replace the fuse. • If the fuse is normal: ― Repair or replace the wiring harness for a possible open circuit. Go to Step 14.
5	INSPECT INTAKE CMP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • Verify that the intake CMP sensor connector is disconnected. • Switch the ignition to off. • Inspect for continuity between intake CMP sensor terminal A (wiring harness-side) and body ground. • Is there continuity?	Yes	If the short to ground circuit could be detected: • Repair or replace the wiring harness for a possible short to ground. If the short to ground circuit could not be detected: • Replace the PCM (short to ground in the PCM internal circuit). (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0].) Go to Step 14.
5		No	Go to the next step.
6	INSPECT PCM CONNECTOR CONDITION • 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 14.

14	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 [SKYACTIV-G 2.0].) • Start the engine. • Perform the KOER self test. (See KOEO/KOER SELF TEST [SKYACTIV-G 2.0].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0].) Go to the next step.
