I repossessed this vehicle. Definitely not been taken care of. I replaced the valve cover. Oil is dirty, so I will be changing it. Didn't have check engine light on until recently. P0014, I know it could be related to dirty or low oil but also could be the VVT or the cam sensor. Where is the cam sensor on this one? Is it on the side of the motor on top of the chain cover? If the vet I want to clean it as well, where is that one located?

Hello, yes, it looks like the Intake cam sensor is on top, notice where the engine hoist bracket is in the 2nd and 3rd diagram that's the Exh cam sensor, the Intake cam sensor will be on the opposite side of the valve cover. Go by wire colors as well, it's a hall effect sensor so it should be 3 wires with a 12v feed. The VVT solenoid is in the 4th diagram, says bottom on intake manifold, but will look for a better location description.

Sorry that was incorrect on the Intake VVT location, the Intake VVT is actually listed as being a motor, which is something that needs more looking into.

This is the other VVT I see besides the Exh VVT, this Electric E-CVVT Motor, which is something new, but that's the wiring for it, the other solenoid I mislabeled was for the intake runner type solenoid.

So this Intake VVT setup is pretty technical, its not an oil controlled solenoid like the exhaust VVT in the 1st diagram, the 2nd diagram is the Intake VVT electric motor. The 3rd, 4th and 5th diagrams are the operations, theyre using an electric motor in this case so theres no difference in performance for the intake VVT regardless of engine oil pressure if I read the service info correctly. Diagrams 6 and 7 showing the scope waveforms when troubleshooting a problem with the intake cam timing. The only issue is the P0014, service info states it is Camshaft Position B Timing Over-Advanced or System Performance (Bank1). It doesnt seem specific to the intake or exhaust camshaft, I thought it was the intake camshaft, but the oil condition can definitely be a cause of that code. Thats where I would start as well.
