P1234 Ford Description
The Powertrain Control Module (PCM) monitors the Fuel Pump Monitor (FPM) circuit from the Fuel Pump Driver Module (FPDM). With the key on, the FPDM continuously sends a duty cycle signal to the PCM through the FPM circuit. The test fails if the PCM stops receiving the duty cycle signal.P1234 Ford Information for specific Ford models
