DTC Code C1440 Preasure Tansducer Problem
I have a 2004 Ford Explorer V8 4w drive. I have two problems that I'm trying to figure out, first problem is that my ABS light comes on, mainly when I quickly hit the gas while turning the wheel(such as passing a car). When I turn the truck off and back on, the light goes off, and stays off till the next time I pass a car or what ever.
Second problem is my cruise control, it sometimes works, and sometimes dosen't. I don't know why. One thing that I did notice is that if the cruise isn't working, it'll sometimes start working again after I bring the truck to a full stop.
I get a dtc code C1440 Preasure Transducer Main Primary Signal Faulted. Any suggestion on the problem and the fix

I know this is an old thread but I have a question. I have the same issue. What are the test procedures to make sure the switch is bad. I understand it is an easy fix but I don't want to throw away $30 if I need to put the money towards another part.
