I have a 2010 santa fe 2.4 with 225 000 km on it. Bought it used. I have changed the oil regularly and maintained it since I got it. I was driving the other day and got a little rough idle and stumble on acceleration. I got a P0011 code I went to check the ocv intake side and the solenoid separated from the actuator leaving it stuck in the head. Got it out fine. It wasn’t dirty at all. Ordered and installed a new one and the code come right back. SUV drives fine starts fine. Any ideas. I changed the oil after I put in the new part.

Possible causes:
Low or Dirty Engine Oil
Faulty Valve Timing Control (VTC)
Valve Timing Control (VTC) harness is open or shorted circuit.
Valve Timing Control (VTC) circuit poor electrical connector
Incorrect timing Engine mechanical problems
Damaged Engine Control Module (ECM)The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the exhaust camshaft. There is no variation in valve timing of the exhaust cam because the exhaust camshaft is driven by the timing belt. The timing of the intake cam is varied by the relative operation the CVVT vane to the housing. The CVVT controller regulates the intake camshaft angle using oil pressure through the OCV (Oil Control Valve). As result, the relative position between the camshaft and the crankshaft becomes optimal, and the engine torque improves, fuel economy improves, exhaust emissions decrease by changing the valve open/close timing of the intake camshaft. The deviation of the camshaft position from the target point is evaluated during stable driving condition. The Engine Control Module (ECM) accumulates this deviation for a certain period and sets DTC P0011 when the accumulated deviation is too high. The target camshaft position is predetermined value depending on engine speed and throttle angle in the ECM.
I have already read all that .
The oil is fine clean and full
I dont think the is an engine mechanical problems. The engine runs good. Starts good tons of pep. Where should I start looking . Is there anywhere to get free wiring diagramsI have already read all that .

Try disconnecting both battery cables from the battery and short them together and let it sit for a while.
Reconnect the cables to the battery, start and drive the car for a while so the computer can relearn the fuel mapping.
If the error code shows up again you may have a deeper issue.
You may have an issue with the CVVT controller or its wiring, the chain sprocket of the exhaust camshaft, the timing chain or one of its components.so i tried resetting the ECU last night. The battery cables are not long enough to touch with the battery in place so i used a jumper wire to short the wires together and left it shorted over night. Today i reconnected the terminals and drove it. After about 10 KM of city driving the light came back on. i had my scan tool with me and checked the codes. and there is 2 P0011
So no difference was made. Again there is no drive ability issues at all, it seems to run fine. once in a wile it stumbles a bit if your on the gas and snap the the throttle closed as if the throttle body might need cleaning. What and i do now. where should i start looking. i haven’t been able to find any wiring diagrams for it anywhere.You may be able to get the wiring schematics here for free… I use this often.

I did a little testing today
Both on the intake cam solenoid and the ehaust are the same. Key off 0.2 volts key on 8.6 volts with the engine running at idle 10.8 volts I checked the ground with a test light and its is definitely not as bright at the connectors compared to just touching the engine. Is it a grounding issue I wonder. I didn’t back probe the connection i just pulled it off for the test would that make any difference.
