A full list of Ford engine trouble codes can be found in the Support section of the Edge Products website. The comprehensive list contains 48 pages of codes in a downloadable PDF format.
Ford engine fault codes are called Diagnostic Trouble Codes, and they are always displayed as one letter followed by four numerals. The first symbol of the DTC indicates at a glance what part of the vehicle is at fault. If the first symbol is a P, then the fault is within the powertrain. B is for body, C is for chassis, and U is for reserved for future systems.
