Posted to Ford Driveability on 10/12/2007 16 Replies

Hey dudes,

This fine ford comes in every 3-6 months for this code (p0401) This last time I checked the dpf sensor and found water in it, Both lines that go into it come from the exhaust below the sensor one is the intake side and the other is the exhaust side...
