    This is a long shot, but I am hoping to obtain an answer to a mechanical engine issue I am having with my 2013 Santa Fe XL 3.3L. Using a diagnostics tool I have discovered that the desired intake phaser timing is not changing from 0 degrees regardless of RPM and load. I have no error codes showing up and the camshaft is making a loud clacking/ticking sound. Here is the live data read out at approximately 2000rpm (regardless of load, i.e. in Park or Drive):

    Intake:
    117 [117]IN-Cam Bank1 Desired Position 0.02 DEG
    118 [118]IN-Cam Bank1 Actual Position -0.12 DEG
    119 [119]IN-Cam Bank2 Desired Position 0.02 DEG
    120 [120]IN-Cam Bank2 Actual Position 0.06 DEG
    121 [121]IN-Cam Phaser 1 Duty Cycle 0.00 %
    122 [122]IN-Cam Phaser 2 Duty Cycle 0.00 %
    Exhaust:
    125 [125]EX-Cam Bank1 Desired Position -10.90 DEG
    126 [126]EX-Cam Bank1 Actual Position -10.55 DEG
    127 [127]EX-Cam Bank2 Desired Position -10.90 DEG
    128 [128]EX-Cam Bank2 Actual Position -11.27 DEG
    129 [129]EX-Cam Phaser 1 Duty Cycle 41.96 %
    130 [130]EX-Cam Phaser 2 Duty Cycle 41.18 %

    As you can see both exhaust VVTs are operating normally, but both the intake phasers never move from zero. I could understand if the desired value changed and the actual value didn’t as that would show signs of a bad solenoid but with the ECU never changing the desired value of both intake phasers and the exhaust phasers are operating normally I am at a loss as to what would cause this.

    Any help would be greatly appreciated.
    Cheers
