This 2014 Hyundai Elantra had over 250,000 kms and ran great. However, it had a DTC code "P0017 Crankshaft position - camshaft position correlation bank 1 sensor b" indicating a problem with crank/cam timing of the Continuously Variable Valve Timing (CVVT) system. CVVT was in Limp Home mode. This is a commmon problem with high mileage Hyundai's of this vintage. This video shows how I diagnosed the P0017 issue, including the removal and testing procedure of the cam valve/solenoids. However, much of the theory in this video is applicable to troubleshooting other CVVT related DTCs.

Possible causes are dirty oil, the camshaft timing control solenoids, camshaft position sensor, crankshaft position sensor or the timing change and its timing gears.

    Why didnt you run power to the solenoid to see if it moves in and out?
