6	INSPECT INTAKE CMP SENSOR POWER SUPPLY CIRCUIT FOR SHORT TO GROUND Inspect the applicable circuit for a short to ground. (See CIRCUIT INSPECTION .) Is the circuit normal?	Yes	Go to the next step.
6		No	Repair or replace the malfunctioning location and perform the repair completion verification.
7	INSPECT INTAKE CMP SENSOR POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT Inspect the applicable circuit for open circuit. (See CIRCUIT INSPECTION .) Is the circuit normal?	Yes	Go to the next step.
7		No	Repair or replace the malfunctioning location and perform the repair completion verification.
8	INSPECT INTAKE CMP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND Inspect the applicable circuit for a short to ground. (See CIRCUIT INSPECTION .) Is the circuit normal?	Yes	Go to the next step.
8		No	Repair or replace the malfunctioning location and perform the repair completion verification.
9	INSPECT PCM CONNECTOR FOR MALFUNCTION Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION .) Are the connector and terminal normal?	Yes	Go to the next step.
9		No	Repair or replace the malfunctioning location and perform the repair completion verification.
10	INSPECT INTAKE CMP SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY Inspect the applicable circuit for a short to power supply. (See CIRCUIT INSPECTION .) Is the circuit normal?	Yes	Go to the next step.
10		No	Repair or replace the malfunctioning location and perform the repair completion verification.
11	INSPECT INTAKE CMP SENSOR SIGNAL CIRCUIT AND GROUND CIRCUIT FOR SHORT CIRCUIT Inspect the applicable circuits for a short circuit. (See CIRCUIT INSPECTION .) Is the circuit normal?	Yes	Go to the next step.
11		No	Repair or replace the malfunctioning location and perform the repair completion verification.
12	INSPECT INTAKE CMP SENSOR SIGNAL CIRCUIT AND GROUND CIRCUIT FOR OPEN CIRCUIT Inspect the applicable circuit for open circuit. (See CIRCUIT INSPECTION .) Is the circuit normal?	Yes	Go to the next step.
12		No	Repair or replace the malfunctioning location and perform the repair completion verification.
13	INSPECT INTAKE CMP SENSOR FOR MALFUNCTION Inspect the applicable part. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [(VIN M) (US)] .) (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [(VIN 7 & VIN L) (US)] .) Is the part normal?	Yes	Go to the next step.
13		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION [(VIN M) (US)] .) (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION [(VIN 7 & VIN L) (US)] .)
14	INSPECT CKP SENSOR CONNECTOR FOR MALFUNCTION Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION .) Are the connector and terminal normal?	Yes	Go to the next step.
14		No	Repair or replace the malfunctioning location and perform the repair completion verification.
15	VERIFY ASSEMBLY CONDITION OF TIMING CHAIN Verify the condition of the timing chain assembly (intake valve timing, looseness, jumping). (See TIMING CHAIN REMOVAL/INSTALLATION [(VIN M) (US)] .) (See TIMING CHAIN REMOVAL/INSTALLATION [(VIN 7 & VIN L) (US)] .) Is there any malfunction?	Yes	Repair or replace the malfunctioning part. Assemble the timing chain using the correct timing and perform the repair completion verification. (See TIMING CHAIN REMOVAL/INSTALLATION [(VIN M) (US)] .) (See TIMING CHAIN REMOVAL/INSTALLATION [(VIN 7 & VIN L) (US)] .)
15		No	Go to the next step.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED Install/connect the part removed/disconnected during the troubleshooting procedure. Clear the DTC recorded in the memory. (See CLEARING DTC .) Replicate the vehicle conditions at the time the DTC was detected using the following procedure. Start the engine and race it. Perform the KOER self test. (See DTC INSPECTION .) Perform the DTC inspection for the PCM. (See DTC INSPECTION .) Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW (US) .) If the CAN communication is normal, perform the diagnosis from Step 1. If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [(VIN M) (US)] .) (See PCM REMOVAL/INSTALLATION [(VIN 7 & VIN L) (US)] .)
Repair completion verification 1		No	Go to the next step.
Repair completion verification 2	VERIFY IF OTHER DTCs DISPLAYED Perform the DTC inspection. (See DTC INSPECTION .) Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
Repair completion verification 2		No	DTC troubleshooting completed.
