    NOTE: Some vehicles require higher RPMs and loads to actuate the VCT system than others. The VCTADVERR PID (Escape 2.5L and Fusion 2.5L), VCT_INT_DIF PID (for all others) or VCT_EXH_DIF PID (for all others) should be close to zero whether actuating or not. During rapid VCT movements, the VCTADVERR PID (Escape 2.5L and Fusion 2.5L), VCT_INT_DIF PID (for all others) or VCT_EXH_DIF PID (for all others) may momentarily deviate from zero.
    NOTE: For a symptom based concern, monitor all applicable PIDs during this step.
    • Clear the PCM DTCs.
    • For Escape 2.5L and Fusion 2.5L:
    • For DTCs P0011, P0012, P0016, P052A and P052B,
    • Access the PCM and monitor the VCTADV (ANGL) and VCTADVERR (ANGL) PIDs.
    • For all others:
    • For DTCs P000A, P0011, P0012, P0016, P052A and P052B,
    • Access the PCM and monitor the VCT_INT_ACT1 (ANGL) and VCT_INT_DIF1 (ANGL) PIDs.
    • For DTCs P000B, P0014, P0015, P0017, P054A and P054B,
    • Access the PCM and monitor the VCT_EXH_ACT1 (ANGL) and VCT_EXH_DIF1 (ANGL) PIDs.
    • For DTCs P0018, P0021, P0022, P052C and P052D,
    • Access the PCM and monitor the VCT_INT_ACT2 (ANGL) and VCT_INT_DIF2 (ANGL) PIDs.
    • For DTCs P0019, P0024, P0025, P054C and P054D,
    • Access the PCM and monitor the VCT_EXH_ACT2 (ANGL) and VCT_EXH_DIF2 (ANGL) PIDs.
    • Drive the vehicle while exercising the throttle to generate VCT movement.

    Does the VCTADV PID (Escape 2.5L and Fusion 2.5L), VCT_INT_ACT PID (for all others) or VCT_EXH_ACT PID (for all others) indicate VCT movement while the VCTADVERR PID (Escape 2.5L and Fusion 2.5L) or VCT_INT_DIF PID (for all others) or VCT_EXH_DIF PID (for all others) maintain close to zero? 

    Yes No
    Unable to duplicate or identify the concern at this time. The concern may have been caused by an oil flow restriction which was removed by opening the VCT solenoid. If the engine runs rough at idle and KOER or continuous memory DTCs are present, GO to  HK12.
    For all others, GO to HK11  .
  11. HK11 CHECK THE FUNCTIONALITY OF THE VCT SYSTEM 
    NOTE: Diagnose the suspect VCT solenoid indicated by the DTC.
    • Ignition OFF.
    • Disconnect the VCT solenoid related to the current DTC.
    • Ignition ON, engine running.
    • Connect a 5 amp fused jumper wire between the following:
      Point A VCT Solenoid Connector, Component Side Point B Vehicle Battery
      VCT Negative terminal
    • Connect a 5 amp fused jumper wire between the following:
      Point A VCT Solenoid Connector, Component Side Point B Vehicle Battery
      VPWR 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.

    REPAIR as necessary.
    Clear the PCM DTCs. REPEAT the self-test.    		 INSTALL a new VCT phaser as necessary. REFER to the appropriate Timing Drive Components article.
    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
