The ECM optimizes the intake valve timing using the VVT (Variable Valve Timing) system to control the intake camshaft. The VVT system includes the ECM, the Oil Control Valve (OCV) and the VVT controller. The ECM sends a target duty-cycle control signal to the OCV. This control signal regulates the oil pressure supplied to the VVT controller. The VVT controller can advance or retard the intake camshaft. If
the difference between the target and actual intake valve timings is large, and changes in actual intake valve timing are small, the ECM interprets this as the VVT controller stuck malfunction and sets a DTC.
You may have inadvertently clogged the OCV filter located on the back of the head passenger side if I remember correctly. Without looking I couldnt tell you. Use correct build up oil when installing new cams. Rtv in the oil system when putting valve cover back together. Im just throwing things out there to help narrow it down.

we pull out the sensor and cleaned it...did NOT see any RTV... there was oil in one of the holes to it but idk if it should have drained out or not but its gone now because the sensor was removed and cleaned

When everything is lined up on the hack marks. What does your cam angle sensor on the other side look like. For some reason the ECU is thinking that cam angle target is off.

Sorry. With all the timing marks lined up and the cover off the intake cam sensor on the driver side, is the paint mark on the sensor up top. Second just to rule it out when the cam belt was off were you able to move the intake cam gear a few degrees either direction.

Well with everything mechanically looking good then I would start looking into an ecu issue which would be Mellons area more than mine. Im sorry I couldnt help out more. Good luck and let us know when you get it solved.

Here is what the FSM says to trouble shoot:
1. Oil feeder control valve.
2. Check oil passage of variable valve timing control system for being clogged.
3. Check variable valve timing sprocket operation mechanism for being stuck.
4. Replace ECM.
This is on a stock car.
What type of mivec map are you using? Is it the JDM RS map?
