Check engine light came on. Gave P200A code to replace intake manifold running solenoid, which I did.

4 days later engine light came back on. This time it said to replace the intake manifold or the manifold motor.

Have not replaced these parts yet. I can turn off the check engine light by disconnecting the battery but when I opened the rear passenger door the light came back on. At times when I shift from park to in gear the rear door locks open and close 3-4 times then work ok.

Have appointment in 5 days at the dealer to spend $200 to do a system check to diagnose the problem. Don't want to keep changing parts not really knowing. The engine has a rough idle when I stop at a red light when the AC is on. Is ok idle when AC is off.

Does anyone tell me please WHAT could be my cars problem.

Thanks Jack Adams

I have a 2011 Santa Fe 3.5 6, FWD, 54k miles, that has been having the check engine light go on and off. Recently with in the pass month and a half the dealership has performed the recall adjustment, changed the manifold intake assy, changed the ECM with all visits rendered a P200A code. After changing the manifold assy, check engine light was off and fuel gauge was at a 1/4 tank. Stop by a gas station and filled up and the light comes on. Remove gas cap after turning off engine and secured gas cap as directed on the cap of one click and light stays on. Turning into the dealership for the 4th time.
