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 (CCM).
•  The MIL does not illuminate.
•  FREEZE FRAME DATA is available.
•  The DTC is 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 clogging and/or leakage
•  Improper adjustment of valve timing
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
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.
No
Go to the next step.
3
INSPECT VARIABLE VALVE TIMING CONTROL SYSTEM OPERATION
•  Perform the Variable Valve Timing Control System Operation Inspection.
•  Does the variable valve timing control system work properly?
Yes
Go to the next step.
No
Repair or replace the malfunctioning part according to the inspection results, then go to Step 9.
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 clogging and/or leakage.
―  Between the oil pressure switch and the OCV
―  Between the OCV and the camshaft
―  The camshaft internal passage
•  Is there any clogging and/or leakage?
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 the 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
•  Make sure to reconnect all disconnected connectors.
•  Turn the ignition switch to the ON position (engine off).
•  Clear the DTC from the PCM memory using M-MDS.
•  Perform the KOER self test.
•  Is same DTC present?
Yes
Replace the PCM, then 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.
