DESCRIPTION

Refer to DTC P0010 (see page Нажмите здесь).

DTC No.
DTC Detection Condition
Trouble Area
P0012
Valve timing on bank 1 intake side remains in retarded position, and there is difference target and actual valve timing for approx. 5 minutes or more
(2 trip detection logic)
  1. Camshaft timing gear assembly (bank 1)
  2. Camshaft timing control motor (bank 1)
P0022
Valve timing on bank 2 intake side remains in retarded position, and there is difference target and actual valve timing for approx. 5 minutes or more
(2 trip detection logic)
  1. Camshaft timing gear assembly (bank 2)
  2. Camshaft timing control motor (bank 2)

MONITOR DESCRIPTION

This DTC is output when a valve timing stuck condition is detected. With the engine speed at 4000 rpm or less in the retard angle position, if the valve timing does not vary, or a large difference in the target and actual valve timing occurs continuously for 5 seconds, it is determined that a malfunction has occurred. If this condition is detected while driving, a DTC is output (2 trip detection logic).
After the engine is warmed up, a DTC is output if the following occurs: 1) the vehicle is driven in an urban area for 5 minutes, and then the engine switch is turned off; and 2) the engine is started and the vehicle is driven in an urban area for 5 minutes.

INSPECTION PROCEDURE

УКАЗАНИЕ:
Intelligent tester only:
By using the Active Test's Control the MD VVT Linear (Bank1) or Control the MD VVT Linear (Bank2) function, it can be determined if the MD VVT system is malfunctioning.
  1. Connect the intelligent tester to the DLC3.
  2. Turn the engine switch on (IG) and turn the tester ON.
  3. Clear the DTC.
  4. Start the engine and warm it up.
  5. Enter the following menus: Powertrain / Engine / Active Test / Control the MD VVT Linear (Bank1) or Control the MD VVT Linear (Bank2) / All Data / MD VVT Aim Angle (Bank1) and MD VVT Change Angle (Bank1) or MD VVT Aim Angle (Bank2) and MD VVT Change Angle (Bank2).
  6. Perform the "Control the MD VVT Linear (Bank1) or Control the MD VVT Linear (Bank2)" operation with the engine speed at 1500 rpm.

    OK:

    Active Test Movement Order
    		Difference between "MD VVT Aim Angle" and "VVT Change Angle"
    0° → 10° → 20° → 40° → 10° → 0° → 10° → END
    		Within 4°

УКАЗАНИЕ:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

1.CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0012 OR P0022)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the engine switch on (IG).

  1. Turn the tester ON.

  1. Enter the following menus: Powertrain / Engine / DTC.

  1. Read DTCs.

2.INSPECT CAMSHAFT TIMING GEAR ASSEMBLY (BANK 1 OR BANK 2)

  1. Turn the engine switch off.

  1. Remove the camshaft timing control motor (see page Нажмите здесь).

  1. Check if the camshaft timing gear assembly's eccentric shaft rotates smoothly.

    OK:
    Rotates smoothly

REPLACE CAMSHAFT TIMING GEAR ASSEMBLY (BANK 1 OR BANK 2) (Нажмите здесь)
OK


3.REPLACE CAMSHAFT TIMING CONTROL MOTOR (BANK 1 OR BANK 2)

  1. Replace the camshaft timing control motor [bank 1 or bank 2] (see page Нажмите здесь).

4.CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

  1. Connect the intelligent tester to the DLC3.

  1. Turn the engine switch on (IG) and turn the tester ON.

  1. Clear the DTC (see page Нажмите здесь).

  1. Start the engine and warm it up.

  1. Enter the following menus: Utility / Check Mode.

  1. Switch the ECM from normal mode to check mode.

  1. Drive the vehicle in an urban area for approximately 5 minutes.

  1. Enter the following menus: DTC INFO / CURRENT CODE.

  1. Read DTC.
