  10. HK10 CONTINUOUS DTCS P0011, P0012, P0016, P052A OR P052B: CHECK THE OPERATION OF THE VCT SYSTEM 
    NOTE: Some vehicles require higher RPMs and loads to actuate the VCT system than others. The VCTADVERR PID should be close to zero whether actuating or not. During rapid VCT movements, the VCTADVERR PID may momentarily deviate from zero. In addition, normal deviation may momentarily move to the end of the scale on a rapid acceleration.
    • Access the PCM and monitor the VCTADV (ANGL) PID.
    • Access the PCM and monitor the VCTADVERR (ANGL) PID.
    • Drive the vehicle while exercising the throttle to generate VCT movement.

    Does the VCTADV PID indicate VCT movement while the VCTADVERR PID maintain close to zero? 

    Yes No
    Unable to duplicate or identify the concern at this time. If the engine runs rough at idle and KOER or Continuous Memory DTCs are present: GO to  HK12.
    For all others, GO to  HK11.

    Point A VCT Solenoid Connector, Component Side Point B Vehicle Battery
    VPWR - Pin 1 Positive terminal

    Does the engine reduce speed, run rough or stall with the jumper connected? 

    Yes No
    The concern is not present at this time.
    The concern may have been caused by an oil flow restriction which was removed by opening the VCT solenoid.
    Clear the PCM DTCs. REPEAT the self-test.    		 GO to  HK12.

      CONNECTOR PINS REFERENCE CHART

      Point A VCT Solenoid Connector, Component Side Point B Vehicle Battery
      VCT - Pin 2 Negative terminal
    • Connect a 5 amp fused jumper wire between the following:
      CONNECTOR PINS REFERENCE CHART

      Point A VCT Solenoid Connector, Component Side Point B Vehicle Battery
      VPWR - Pin 1 Positive terminal
    • Listen for an audible click in the VCT solenoid.
    • Repeat as necessary to verify the VCT solenoid click.

    Does the VCT solenoid click? 

    Yes No
    GO to  HK13. INSTALL a new VCT solenoid.
    REFER to the ELECTRONIC ENGINE CONTROLS (HYBRID)
    Clear the PCM DTCs. REPEAT the self-test.
  13. HK13 CHECK THE BASE ENGINE OIL PRESSURE 

    Are any concerns present? 

    Yes No
    REPAIR as necessary.
    Clear the PCM DTCs. REPEAT the self-test.    		 INSTALL a new VCT phaser as necessary.
    REFER to the ENGINE MECHANICAL - 2.5L (HYBRID) , Timing Drive Components.
    Clear the PCM DTCs. REPEAT the self-test.
  14. HK14 CHECK FOR CORRECT PCM OPERATION 
    • Disconnect all the PCM connectors.
    • Visually inspect for:
      • pushed out pins
      • corrosion
    • Connect all the PCM connectors and make sure they seat correctly.
    • Carry out the PCM self-test.
    • Verify the concern is still present.

    Is the concern still present? 

    Yes No
    INSTALL a new PCM. REFER to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) , PROGRAMMING THE VID BLOCK FOR A REPLACEMENT PCM . The system is operating correctly at this time.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
