DTC P1384[ZJ, ZY, Z6]

id0102c1836700


Without Throttle Valve Actuator

DTC P1384

Variable valve timing control system operation error
DETECTION CONDITION
Diagnostic support note
•  The PCM monitors the actual valve timing and desired valve timing. If the difference between actual valve timing and desired valve timing is bigger than the preprogrammed criteria at the KOER, the PCM determines the variable valve timing control system operation error.
•  This is not a continuous monitor (CCM).
•  The MIL dose not illuminates.
•  FREEZE FRAME DATA is not available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  Low engine oil pressure
•  OCV malfunction
•  Variable valve timing actuator malfunction
•  Following oil runners are clogged or have leakage
Oil runners
•  Between oil pressure switch and OCV
•  Between OCV and variable valve timing actuator
•  In variable valve actuator
•  CMP sensor malfunction
•  Loose timing chain or improper valve timing due to timing chain slippage

Yes
Repair or replace suspected runner, then go to the next step.
No
Variable valve timing mechanism is normal.
Note
•  This DTC is detected by intermittent concern.
•  Intermittent concern might be removed by cleaning mode of variable valve timing control function.
Go to the next step.
9
VERIFY TIMING CHAIN INSTALLATION
•  Is camshaft-timing mark at correct point?
Yes
Go to the next step.
No
Reinstall the timing chain, then go to the next step.
(See TIMING CHAIN REMOVAL/INSTALLATION[ZJ, ZY, Z6].)
10
VERIFY TROUBLESHOOTING OF DTC P1384 COMPLETED
•  Make sure to 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
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION[ZJ, ZY, Z6].)
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
•  Perform "After Repair Procedure".
•  Are any DTCs present?
Yes
Go to the applicable DTC troubleshooting.
(See DTC TABLE[ZJ, ZY, Z6].)
No
Troubleshooting completed.


With Throttle Valve Actuator

DTC P1384

Oil Control Valve (OCV) circuit malfunction
DETECTION CONDITION
