SOURCE: diagnostic code p0013, p0014
Diagnostic Test Code (DTC) P0013 is "Exhaust Cam Position (CMP) Actuator Solenoid Control Circuit"
Diagnostic Test Code (DTC) P0014 is "Exhaust Cam Position (CMP) System Performance"
DTC P0014 can be caused by several things that can affect your variable cam timing system performance including using the wrong viscosity engine oil. However, since you have the DTC P0013, it is pretty obvious that the problem is being caused by a circuit malfunction in the control solenoid circuit. It could be as simple as a loose connection at the solenoid electrical connector. It could be that the solenoid itself has an open circuit in its coil windings, or it could even be caused by squirrels or mice chewing on the wiring harnesses in your engine compartment. You must diagnose the circuit to find the cause. Fixing the control solenoid circuit will most likely make both of these codes go away.

Two possibilities, poor electrical connection at the cam position actuator sensor (CPAS) connector or a clogged CPAS. Check connector first for oil residue. The CPAS itself is prone to clog if the oil is not changed at the proper intervals. Unfortunately, the CPAS is a little difficult to remove since access to one of its bolts requires the removal of the power steering pump.
