Description
Bosch 0281006325 is an OE fuel rail pressure (FRP) sensor for the 2003-2007 Dodge Ram 2500 / 3500 with the 5.9L Cummins ISB common-rail engine. The sensor threads into the high-pressure fuel rail and feeds rail pressure to the ECM for closed-loop fuel injection control. As the OE supplier of the 5.9L common-rail fuel system, Bosch supplies this sensor to the same specification as the original-fit unit.
Signs You Need a New Fuel Rail Pressure Sensor
- DTC P0192, P0193 (FRP sensor circuit low/high) or P0087/P0088 (rail pressure too low/high)
- Hard starting, no-start, or extended cranking
- Loss of power, derate, or limp-mode under load
- Surging, hesitation, or rough idle
- Erratic rail-pressure data on a scan tool
