Fuel Pump Driver Module (FPDM)
WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The FPDM receives a duty cycle signal from the powertrain control module (PCM) and controls the fuel pump operation in relation to this duty cycle. This results in variable speed fuel pump operation. The FPDM sends diagnostic information to the PCM on the fuel pump monitor circuit. For additional information, refer to FUEL PUMP (FP) and FUEL PUMP MONITOR .
