P1233 2008 Ford Fusion 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.
