What does this Cummins 5.9L Fuel Pressure Sensor Do?
- This Mopar 5093112AA fuel pressure sensor senses the amount of fuel in the fuel rail by reading the internal pressure of the rail.
- The pressure sensor then sends an electronic message to the Power Control Module PCM telling it precisely how much fuel needs to be released into the engine.
- The fuel rail pressure sensor measures the pressure of the fuel being supplied to the fuel injectors.
- This pressure signal is used by the PCM to adjust the fuel injector pulse width and duration while metering fuel to each cylinder during the combustion cycle.
