Fuel Pump Monitor (FPM) - All Others: Notes
WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2017 Lincoln Navigator, 2017 Lincoln MKZ, 2017 Lincoln MKX, 2017 Lincoln MKT, and 2017 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The Continental 3.0L, Focus 2.3L, Ford GT and MKZ 3.0L use 2 fuel pump control modules to control fuel for the fuel delivery system. The PCM individually monitors both fuel pump control modules through the FPM and FPM2 circuits.
The fuel pump control module communicates diagnostic information to the PCM through the FPM circuit. This information is sent by the fuel pump control module as a duty cycle signal. The duty cycle signals that may be sent are listed in the following tables.
