DTC P0011: Variable Valve Timing System Target Error
 
 
 
 
TECHNICAL DESCRIPTION
  • The ECM checks the variable valve timing system for malfunction.
 
 
DESCRIPTIONS OF MONITOR METHODS
  • The difference between the actual intake valve opening timing and the intake valve target opening timing is over the specified value.
 
 
MONITOR EXECUTION
  • Continuous
 
 
MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC set in memory for the item monitored below)
  • Not applicable
Sensor (The sensor below is determined to be normal)
  • Camshaft position sensor
  • Crankshaft position sensor
  • Engine coolant temperature sensor
  • Throttle position sensor
  • Engine oil control valve
 
 
DTC SET CONDITIONS
Logic Flow Chart
Check Conditions
  • More than 20 seconds have passed since the engine starting sequence was completed.
  • Engine speed is higher than 1,188 r/min.
  • Engine coolant temperature is higher than 76°C (169°F).
Judgment Criterion
  • The difference between the actual intake valve opening timing and the intake valve target opening timing is more than 5 degrees for 5 seconds.
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • None.
 
 
OBD-II DRIVE CYCLE PATTERN
  • Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 4 .
 
 
TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:)
  • Engine oil control valve failed.
  • Oil passage of variable valve timing control system clogged.
  • Intake variable valve timing sprocket operation mechanism stuck.
  • ECM failed.

 
 
DIAGNOSIS
STEP 1. Using scan tool (M.U.T.-IIISE), read the diagnostic trouble code (DTC).
cautionTo prevent damage to scan tool (M.U.T.-IIISE), always turn off the power supply mode of the electric motor switch before connecting or disconnecting scan tool (M.U.T.-IIISE).
(1) Connect scan tool (M.U.T.-IIISE). Refer to HOW TO CONNECT THE SCAN TOOL (M.U.T.-IIISE) .
(2) Turn on the power supply mode of the electric motor switch.
(3) Read the DTC.
(4) Turn off the power supply mode of the electric motor switch.
Is the diagnostic trouble code other than P0011 set?
Refer to Diagnostic Trouble Code Chart .
Go to Step 2.
 
STEP 2. Check engine oil control valve itself.
  • Refer to Engine Oil Control Valve Check .
Is the check result normal?
Go to Step 3.
Replace engine oil control valve. Then go to Step 6.
 
STEP 3. Check oil passage of variable valve timing control system for being clogged.
Is the check result normal?
Go to Step 4.
Repair it. Then go to Step 6.
 
STEP 4. Check variable valve timing sprocket operation mechanism for being stuck.
Is the check result normal?
Go to Step 5.
Repair it. Then go to Step 6.
 
STEP 5. Check the trouble symptoms.
(1) Carry out test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 4 .
(2) Check the diagnostic trouble code (DTC).
Is DTC P0011 set?
Replace the ECM (Refer to Removal and Installation ). Then go to Step 6.
It can be assumed that this malfunction is intermittent. Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions .
 
STEP 6. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 4 .
(2) Check the diagnostic trouble code (DTC).
Is DTC P0011 set?
Retry the troubleshooting.
The inspection is complete.
