Step 6-8
- Perform an engine oil related inspection.
Repair completion verification
- Verify that the primary malfunction is resolved and there are no other malfunctions.

P0014-00 (PCM (PYUL)) DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	PURPOSE: VERIFY IF SPOOL VALVE IN OIL CONTROL VALVE (OCV) IS STUCK Switch the ignition off. Remove the oil control valve (OCV). (Refer to [HYDRAULIC VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION ] in Service Information). Inspect the oil control valve (OCV). (Refer to [HYDRAULIC VARIABLE VALVE TIMING ACTUATOR INSPECTION ] in Service Information). Can the spool valve in oil control valve (OCV) operation be verified?	Yes	Go to the next step.
1		No	Replace the oil control valve (OCV) and perform the repair completion verification 1. (Refer to [HYDRAULIC VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION ] in Service Information).
2	PURPOSE: INSPECT ENGINE OIL LEVEL Inspect the engine oil level. (Refer to [ENGINE OIL LEVEL INSPECTION ] in Service Information). Is the engine oil level sufficient?	Yes	Go to the next step.
2		No	Add genuine engine oil and perform the repair completion verification 1. (Refer to [ENGINE OIL REPLACEMENT ] in Service Information).
3	PURPOSE: DETERMINE INTEGRITY OF HYDRAULIC VARIABLE VALVE TIMING ACTUATOR Inspect the hydraulic variable valve timing actuator. (Refer to [HYDRAULIC VARIABLE VALVE TIMING ACTUATOR INSPECTION ] in Service Information). Is there any malfunction?	Yes	Replace the hydraulic variable valve timing actuator and perform the repair completion verification 1. (Refer to [HYDRAULIC VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION ] in Service Information).
3		No	Go to the next step.
4	PURPOSE: VERIFY ASSEMBLY CONDITION OF TIMING CHAIN Verify the condition of the timing chain assembly (exhaust valve timing, looseness, jumping). (Refer to [TIMING CHAIN REMOVAL/INSTALLATION ] in Service Information). Is there any malfunction?	Yes	Repair or replace the malfunctioning part. Assemble the timing chain using the correct timing. (Refer to [TIMING CHAIN REMOVAL/INSTALLATION ] in Service Information). Perform the repair completion verification 1.
4		No	Go to the next step.
5	PURPOSE: VERIFY IF FOREIGN MATTER ON EXHAUST CMP SENSOR DETECTION AREA AFFECTS DIAGNOSTIC RESULTS Visually inspect for exhaust CMP sensor. (Refer to [CAMSHAFT POSITION (CMP) SENSOR INSPECTION ] in Service Information). Is there foreign matter such as metallic dust on the exhaust CMP sensor detection area?	Yes	Remove the foreign matter and perform the repair completion verification 1.
5		No	Go to the next step.
6	PURPOSE: INSPECT IF INSUFFICIENT HYDRAULIC PRESSURE CAUSED BY USE OF UNSPECIFIED ENGINE OIL Is the specified engine oil being used?	Yes	Go to the next step.
6		No	Replace the engine oil with genuine engine oil. (Refer to [ENGINE OIL REPLACEMENT ] in Service Information). Perform the [ENGINE OIL DATA RESET] and perform the repair completion verification 1. (Refer to [ENGINE OIL DATA RESET ] in Service Information).
7	PURPOSE: INSPECT ENGINE OIL PRESSURE Inspect the engine oil pressure. (Refer to [OIL PRESSURE INSPECTION ] in Service Information). Is there any malfunction?	Yes	Go to the next step.
7		No	Perform the repair completion verification 1.
8	PURPOSE: VERIFY IF MALFUNCTION RELATED TO ENGINE OIL LEAK OR RESTRICTION AFFECTS DIAGNOSTIC RESULTS Start the engine. Verify if there is engine oil leakage in the oil passage or restriction. Is there engine oil leakage in the oil passage or restriction?	Yes	Repair or replace the malfunctioning part. Add genuine engine oil and perform the repair completion verification 1. (Refer to [ENGINE OIL REPLACEMENT ] in Service Information).
8		No	Go to the next step.
Repair completion verification 1	PURPOSE: 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. Implement the repeatability verification procedure. (See Repeatability Verification Procedure ) 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 MALFUNCTION DIAGNOSIS FLOW [CONTROLLER AREA NETWORK (CAN)] ) 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. (Refer to [PCM REMOVAL/INSTALLATION ] in Service Information).
Repair completion verification 1		No	Go to the next step.
Repair completion verification 2	PURPOSE: VERIFY IF OTHER DTCs DISPLAYED Perform the DTC inspection. (See DTC INSPECTION ) Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning location according to the applicable DTC troubleshooting.
Repair completion verification 2		No	DTC troubleshooting completed.
