CEL code is 3012
 

I recently had replaced the valve cover due to crank case vent valve being broke. Install went great, no more loud whistling noises. But now my car went into limp mode and thrown code 3012. This is a camshaft code and more specific it's on the exhaust side. We changed out the sensors and also swapped with intake side,but still no luck. Any help is appreciated
