Fuel Pump Monitor (FPM) - All Others: Notes
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.
Fuel Pump Control Module Duty Cycle Signals (Continental 2.0L, Continental 2.7L, Continental 3.0L, Edge 2.0L, Edge 2.7L, Escape/Kuga 1.5L, Escape/Kuga 2.0L, Expedition, Explorer 2.3L, Explorer 3.5L GTDI, F-150, Fiesta 1.0L, Fiesta 1.6L GTDI, Focus, Ford GT, Fusion 1.5L, Fusion 2.0L, Fusion 2.7L, MKC, MKT 2.0L, MKX 2.0L, MKX 2.7L, MKZ, Mustang 2.3L, Navigator, Taurus 2.0L)
FUEL PUMP CONTROL MODULE DUTY CYCLE SIGNALS (CONTINENTAL 2.0L, 2.7L, 3.0L, EDGE 2.0L, 2.7L, ESCAPE/KUGA 1.5L)
| Duty Cycle | Comments |
|---|---|
| 20% | This duty cycle indicates the fuel pump control module is receiving an invalid duty cycle from the PCM. |
| 60% | This duty cycle indicates the fuel pump control module is functioning normally. |
| 80% | This duty cycle indicates the fuel pump control module is detecting a concern with the secondary circuits. |
FUEL PUMP CONTROL MODULE DUTY CYCLE SIGNALS (ALL OTHERS)
| Duty Cycle | Comments |
|---|---|
| 20% | This duty cycle indicates the fuel pump control module is receiving an invalid duty cycle from the PCM. |
| 40% | For vehicles with event notification signal, this duty cycle indicates the fuel pump control module is receiving an invalid event notification signal from the RCM. For vehicles without event notification signal, this duty cycle indicates the fuel pump control module is functioning normally. |
| 60% | For vehicles with event notification signal, this duty cycle indicates the fuel pump control module is functioning normally. |
| 80% | This duty cycle indicates the fuel pump control module is detecting a concern with the secondary circuits. |
