DTC P1384:00

OCV circuit malfunction

DETECTION CONDITION
•  If any of the following conditions are met during the KOER self test:
―  The PCM cannot control the actual valve timing at the target valve timing.
―  The PCM cannot hold the valve timing.
Diagnostic support note
•  This is a continuous monitor (other).
•  The check engine light does not illuminate.
•  FREEZE FRAME DATA (Mode 2)/Snapshot data is not available.
•  DTC is not stored in the PCM memory.
POSSIBLE CAUSE
•  Improper operation of variable valve timing control system
•  CMP sensor malfunction
•  OCV malfunction
•  Variable valve timing actuator malfunction
•  Hydraulic passages blockage and/or leakage
•  Improper adjustment of valve timing
•  PCM malfunction

Diagnostic Procedure

STEP

INSPECTION

ACTION

1
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.
No
Go to the next step.
2
VERIFY RELATED PENDING CODE AND STORED DTC
•  Switch the ignition off, then ON (engine off).
•  Verify the related PENDING CODE and stored DTCs using the M-MDS.
•  Are any other DTCs present?
Yes
Go to the appropriate DTC inspection.
No
Go to the next step.
3
INSPECT VARIABLE VALVE TIMING CONTROL SYSTEM OPERATION
•  Perform the Variable Valve Timing Control System Operation Inspection.
•  Is there any malfunction?
Yes
Repair or replace the malfunctioning part according to the inspection results, then go to Step 9.
No
Go to the next step.
4
INSPECT CMP SENSOR
•  Inspect the CMP sensor for the following:
―  CMP sensor installation condition
―  Foreign materials on CMP sensor
―  CMP sensor pulse wheel condition (lack-off protrusion)
•  Is there any malfunction?
Yes
Repair or replace the malfunctioning part according to the inspection results, then go to Step 9.
No
Go to the next step.
5
INSPECT OCV
•  Inspect the OCV.
•  Is there any malfunction?
Yes
Replace the OCV, then go to Step 9.
No
Go to the next step.
6
INSPECT VARIABLE VALVE TIMING ACTUATOR
•  Inspect the variable valve timing actuator.
•  Is there any malfunction?
Yes
Replace the variable valve timing actuator, then go to Step 9.
No
Go to the next step.
7
INSPECT HYDRAULIC PASSAGE FOR VARIABLE VALVE CONTROL SYSTEM
•  Inspect the following hydraulic passages for blockage and/or leakage.
―  Between oil pressure switch and OCV
―  Between OCV and camshaft
―  The camshaft internal passage
•  Is there any malfunction?
Yes
Repair or replace the malfunctioning part according to the inspection results, then go to Step 9.
No
Go to the next step.
8
INSPECT VALVE TIMING
•  Inspect the valve timing. (verify that the timing mark is within specification.)
•  Is there any malfunction?
Yes
Adjust the valve timing properly, then go to the next step.
No
Go to the next step.
9
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the KOER self test.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
10
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
