RE: EGR Problem P0401
Yeah, there is actually a TSB. Only certain years have DPFE's. I replace at least 2 a day on FORD cars/trucks because of this code. And it fixes it. The light never comes back on. What happens is water from the exhaust gets into the sensor and faults them. Did you clear the KAM after doing it?
<-- This has nothing to do with a DPFE.
Do our cars have a DPFS (differential pressure feedback sensor) Ive read of guys replacing those and the light going off.
