P0021 Camshaft Position "A" - Timing Over-Advanced or System Performance (Bank 2)

DESCRIPTION

Refer to DTC P0010 Click here.

DTC No. DTC Detection Condition Trouble Area
P0011

With engine warmed up and idling, intake side (bank 1) valve timing does not change for 1 min. or more in advanced position, and target and actual valve timing do not match

(1 trip detection logic)

 Camshaft timing gear assembly (for Bank 1)
P0021

With engine warmed up and idling, intake side (bank 2) valve timing does not change for 1 min. or more in advanced position, and target and actual valve timing do not match

(1 trip detection logic)

 Camshaft timing gear assembly (for Bank 2)
CAMSHAFT CONTROL MOTOR SYMPTOMS AND FAIL-SAFE DURING MALFUNCTION
Vehicle Condition Fail-Safe

  • Deterioration of driving performance as result of engine combustion degradation

  • Engine output deficiency

  • Idling up (misfire prevention), or power to camshaft timing control motor is cut

  • Valve timing of bank that is operating normally is fixed at maximum retard angle

MONITOR DESCRIPTION

This DTC is output when a valve timing fixed condition is detected. When the valve timing is in the advance angle position, if the valve timing does not vary, and there is a large difference in the target and actual valve timing, it is determined that a malfunction has occurred. When this malfunction is detected, a DTC is output immediately (1 trip detection logic). After the engine is warmed up, if the vehicle is idled for 5 minutes, a DTC is output.

INSPECTION PROCEDURE

Tech Tips


  • By using the Active Test's Control the VVT-iE Linear (Bank1) or Control the VVT-iE Linear (Bank2) function, it can be determined if the VVT-iE system is malfunctioning.


    1. Connect the intelligent tester to the DLC3.

    2. Put the engine in inspection mode Click here.

    3. Turn the tester ON.

    4. Clear the DTC Click here.

    5. Warm up the engine.

    6. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT-iE Linear (Bank1) or Control the VVT-iE Linear (Bank2) / All Data / VVT-iE Aim Angle #1 and VVT Change Angle #1 or VVT-iE Aim Angle #2 and VVT Change Angle #2.

    7. Perform the Active Test operation with the engine speed at 1500 rpm.

      OK
      Active Test Movement Order Difference between "VVT-iE Aim Angle" and "VVT Change Angle"
      0 deg → 10 deg → 20 deg → 40 deg → 10 deg → 0 deg → 10 deg → END Within 4 DegFR

  • Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition 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.

  • When viewed from the rear of the engine assembly, Bank 1 is on the left side and Bank 2 is on the right side.

PROCEDURE


  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0011 OR P0021)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the tester ON.

    4. Enter the following menus: Powertrain / Engine and ECT / DTC.

    5. Read DTCs.
