Function Explanation (DTC Detection Outline)
With the preconditions met, the PCM verifies the conformity of the actual timing relative to the target valve timing. If it does not conform to the normal determination range (difference between target valve timing and actual valve timing is 20 degrees or less) during the malfunction determination period (approx. 5 s), even if the target valve timing is set to the retard side, the PCM determines an excess advance malfunction condition and stores a DTC.
Repeatability Verification Procedure
Warm up the engine to allow the engine coolant temperature to reach 80 °C {176 °F} or more.
Shift to 2nd gear and rapidly accelerate the vehicle to 50 km/h {31 mph} (to operate hydraulic variable valve timing control).
Decelerate to idling.
Shift to 2nd gear and rapidly accelerate the vehicle to 50 km/h {31 mph} again.

STEP |
INSPECTION |
RESULTS |
ACTION |
1 |
PURPOSE: VERIFY RELATED REPAIR INFORMATION AVAILABILITY
|
Yes |
Perform repair or diagnosis according to the available repair information.
|
No |
Go to the next step. |
||
2 |
PURPOSE: RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION NOTE:
|
— |
Go to the next step. |
3 |
PURPOSE: VERIFY IF DIAGNOSTIC RESULT IS AFFECTED BY OTHER RELATED DTCs OCCURRING
|
Yes |
Go to the applicable PENDING CODE or DTC inspection. (See DTC P0335:00 [PCM (SKYACTIV-G 2.0)].) (See DTC P0365:00 [PCM (SKYACTIV-G 2.0)].) (See DTC P2090:00 [PCM (SKYACTIV-G 2.0)].) (See DTC P2091:00 [PCM (SKYACTIV-G 2.0)].) Go to the next step. |
No |
Go to the next step. |
||
4 |
PURPOSE: VERIFY IF DIAGNOSTIC RESULT IS AFFECTED BY DTC OCCURRING FROM OIL PRESSURE SWITCH
|
Yes |
Go to the applicable PENDING CODE or DTC inspection. (See DTC P0524:00 [PCM (SKYACTIV-G 2.0)].) Go to the next step. |
No |
Go to the next step. |
||
5 |
PURPOSE: VERIFY CONFORMITY OF ACTUAL EXHAUST VALVE TIMING AND DETERMINE IF MALFUNCTION IS CAUSED BY OCV OR CONNECTOR RELATED
|
Yes |
Go to Step 7. |
No |
Go to the next step. |
||
6 |
PURPOSE: VERIFY IF SPOOL VALVE IN OCV IS STUCK
|
Yes |
Go to the troubleshooting procedure to perform the procedure from Step 4.
|
No |
Replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 2.0].) Go to the troubleshooting procedure to perform the procedure from Step 8. |
||
7 |
PURPOSE: VERIFY CONNECTOR CONNECTIONS
|
Yes |
Repair or replace the applicable wiring harness or connector parts. Go to the troubleshooting procedure to perform the procedure from Step 8. |
No |
Go to the troubleshooting procedure to perform the procedure from Step 4.
|
Troubleshooting Diagnostic Procedure
Intention of troubleshooting procedure
Step 1—2
Perform an inspection of the hydraulic variable valve timing drive parts.
Step 3
Inspect the exhaust CMP sensor detection areas for adhesion of foreign matter.
Step 4—7
Perform an engine oil related inspection.
Step 8—9
Verify that the primary malfunction is resolved and there are no other malfunctions.
STEP |
INSPECTION |
RESULTS |
ACTION |
1 |
PURPOSE: DETERMINE INTEGRITY OF HYDRAULIC VARIABLE VALVE TIMING ACTUATOR
|
Yes |
Replace the hydraulic variable valve timing actuator, then go to Step 8. |
No |
Go to the next step. |
||
2 |
PURPOSE: VERIFY ASSEMBLY CONDITION OF TIMING CHAIN
|
Yes |
Repair or replace the malfunctioning part. Assemble the timing chain using the correct timing, then go to Step 8. |
No |
Go to the next step. |
||
3 |
PURPOSE: VERIFY IF FOREIGN MATTER ON EXHAUST CMP SENSOR DETECTION AREA AFFECTS DIAGNOSTIC RESULTS
|
Yes |
Remove the foreign matter, then go to Step 8. |
No |
Go to the next step. |
||
4 |
PURPOSE: INSPECT IF INSUFFICIENT HYDRAULIC PRESSURE CAUSED BY USE OF UNSPECIFIED ENGINE OIL
|
Yes |
Go to the next step. |
No |
Replace the engine oil with genuine motor oil, then go to Step 8. |
||
5 |
PURPOSE: INSPECT ENGINE OIL LEVEL
|
Yes |
Go to the next step. |
No |
Add genuine motor oil, then go to Step 8. |
||
6 |
PURPOSE: INSPECT ENGINE OIL PRESSURE
|
Yes |
Go to the next step. |
No |
Go to Step 8. |
||
7 |
PURPOSE: VERIFY IF MALFUNCTION RELATED TO ENGINE OIL LEAK OR RESTRICTION AFFECTS DIAGNOSTIC RESULTS
|
Yes |
Repair or replace the malfunctioning part according to the inspection results. Add genuine motor oil, then go to the next step. |
No |
Go to the next step. |
||
8 |
PURPOSE: VERIFICATION OF VEHICLE REPAIR COMPLETION
|
Yes |
Repeat the inspection from Step 1.
Go to the next step. |
No |
Go to the next step. |
||
9 |
PURPOSE: VERIFY IF THERE IS ANY OTHER MALFUNCTION
|
