Many thanks for the additional info. My 2 codes are P0642 sensor reference voltage “A” circuit is too low and P2004 intake manifold runner stuck open.
Can you tell me if on a 2010 Focus if the Flaps are Open or Closed when there is no vacuum in the actuator and the little white ball joint is up and easily visible while looking at the top of the engine? I assume that this is the Open position?
Thanks again, Mike
