  4. ChapmanF replied to the thread Advice Needed! P0401, P0300, P0301, P0303 Head Gasket and/or EGR?.

  6. ChapmanF replied to the thread Advice Needed! P0401, P0300, P0301, P0303 Head Gasket and/or EGR?.

    Yes, that stops the rotor at the "valve fully closed" position. There is no valve position sensor. There is nothing there but a stepper...
