I have a 1999 ford windstar Lx w/144,000 on it. it threw a 401 engine code. what is it and can u help me out?
P0401 is for the DPFE sensor for the EGR system. Replace the DPFE (Differential Pressure Feedback Sensor). It is located in the left hand rear of the engine. It has 2 black rubber hoses going to it. It should be black and about 2" square.
