2003-2007 DODGE 5.9L CUMMINS FUEL CONTROL ACTUATOR (FCA) - MPROP 0928400666
NEW BOSCH UNIT!
Bosch Fuel Control Actuator (FCA/MPROP)
The function of the part is to control the output pressure of the high pressure CP3 fuel pump. When the part fails, the
actual fuel pressure will not match the desired fuel pressure as specified by the engine computer. Both pressures can be
monitored on a scan tool and compared. The most common symptom as the part begins to fail is varying / unstable idle.
The MPROP is mounted on the back side of the CP3 pump and is attached by (3) T-25 Torx head screws. Two o-rings seal the
MPROP to the pump and are included already installed on the new part.
COMMON DTC TROUBLE CODES:
- DTC P0087 Fuel Rail Pressure (FRP) Too Low
- DTC P0088 Fuel Rail Pressure (FRP) Too High
- DTC P0089 Fuel Pressure Regulator Performance
- DTC P0090 Fuel Pressure Regulator Control Circuit
