Hi Missy,

These codes are for your variable cam timing system. Basically, it is saying that intake cam actuator on bank 1 has an open circuit.

I included the wiring diagram to show this circuit. It goes from the PCM pin 67 violet and light blue wire, to the actuator/solenoid pin 2.

You need to disconnect the wire at both ends and measure continuity or resistance to see whether it is open or not. You should have 0.5 ohms or less of resistance. I imagine it will be okay but that means you need to check the solenoid itself for an open. You do this by measuring resistance between pin 1 and pin 2 of the solenoid. If this is open or infinite resistance, then you need to replace it. I included the procedure on how to replace this in case this is your issue.
