2016 Kia optima 2.4 with code P0100 /camshaft actuator open circuit.

this car came in with this code p010000 indication an open on the cam actuator. the customer changed the part and also inspected the wiring. that's when he contacted me to perform a harness check. I checked for continuity and did a load test and passed. I also scoped the vvt and tried commanding it with the scan tool but wouldn't actuate. reason for this was because the code comes up right away and disables the feature. I scoped and started the car and saw that the pcm saw did comand the actuator and quickly defaults it and won't comand again. this indicates the pcm is trying. I decided to take off the actuator and right away saw the wear on one of the contacts. the phaser will have to be replaced

I’m having this exact same problem I already replaced the cover assembly and both sensors are good just not making contact w the actuator . Did you fix it when you replaced the actuator?

@Imthefelix3 yes replacing the unit with a new one will fix the problem in this case.

@@elitemobileautoelectric7782how long is it to replace the actuator? The timing chain has to come off correct? Is this something a mechanically inclined person can do themselves? Cheers

@Mark-mb3tw the timing does not have to come off. The actuator fairly comes off quick and easy maybe a 10min job.
