Anyone have an idea of why Im throwing this code: P1401 Differential Pressure Feedback Electronic Sensor circuit High Voltage. After I installed my new intake manifold this code keeps coming up. I know the valve isnt leaking because I didnt even have to take that off the plenum. Any ideas? :dunno
did you by chance bend the egr pipe? the pipe that goes down to the exhaust....one of the things the manual says to check is make sure this pipe isnt clogged.
I'm looking at the ford service manual, the part its refering to doesnt look right in the picture....here take a look...
