Code No. P0011: Inlet Variable Valve Timing System
 
 
 
 
OPERATION
  • Check code No. P0010: Inlet oil feeder control valve system (Refer to ).
 
 
FUNCTION
  • The engine-ECU controls the spool valve position of the inlet oil feeder control valve corresponding to the driving condition of the engine and continuously changes the phase of the inlet camshaft.
  • The phase angle of the inlet camshaft is computed from the signal patterns of the crank angle sensor and inlet camshaft position sensor.
 
 
TROUBLE JUDGEMENT
Check Conditions
  • More than 20 seconds have passed since the engine starting sequence was completed.
  • Engine speed is more than 1,200 r/min.
  • Engine coolant temperature is more than 76°C.
Judgement Criterion
  • Difference between inlet valve open timing and target inlet valve open timing is more than 5°CA for 5 seconds.
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • None
 
 
PROBABLE CAUSES
  • Failed inlet oil feeder control valve
  • Harness damage in inlet oil feeder control valve circuit or loose connector contact
  • Failed timing sprocket operation
  • Clogged oil passage
  • Failed inlet camshaft
  • Failed engine-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE data list
  • Data list reference table (Refer to ).
    1. Item 36: Inlet V.V.T. phase angle
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Go to Step 2.
 
STEP 2. Check inlet oil feeder control valve itself.
  • Inlet oil feeder control valve check (Refer to ).
Is the check result normal?
Go to Step 3.
Replace the inlet oil feeder control valve.
 
STEP 3. Check of damage in OCVI line between inlet oil feeder control valve connector and engine-ECU connector.
Is the check result normal?
Go to Step 4.
Repair the connector(s) or wiring harness.
 
STEP 4. Check of damage in power supply line between engine control relay connector and inlet oil feeder control valve connector.
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
 
STEP 5. Check inlet camshaft sensing ring.
Is the check result normal?
Go to Step 6.
Replace the inlet camshaft.
 
STEP 6. Check inlet variable valve timing sprocket operation mechanism for being stuck.
  • Check inlet variable valve timing sprocket
    (Refer to GROUP 11B - Timing Chain - Inspection ).
Is the check result normal?
Go to Step 7.
Repair.
 
STEP 7. Check oil passage of inlet variable valve timing control system for being clogged.
Is the check result normal?
Go to Step 8.
Repair.
 
STEP 8. M.U.T.-IIISE diagnosis code
  • Reconfirmation of diagnosis code.
Is the diagnosis code set?
Replace the engine-ECU.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
