Drivers can obtain codes from a Ford truck with a code scanner device and compare them with code listings on FordF150.net. The site features diagnostic trouble code listings for Ford trucks with EEC-V processors, such as late-model Ford F150s.
The code scanner device returns a number when a Ford truck needs repairs, and the number indicates what is wrong the vehicle. For example, the code number P0300 indicates a random misfire on a Ford truck with an EEC-V processor.
As of April 2015, FordF150.net features new odometer test codes added to newer Ford F150s and EEC-V processor trucks. New codes include odometer memory failure and oil pressure switch failure, among others.
