Cummins Isx Fuel Rail Pressure Sensor

Replacement restores engine performance.

Cummins isx fuel rail pressure sensor.

Pressure side fuel filter inlet 9. Pressure side fuel filter 5 micron 10. 2013 peterbelt 386 isx 15 cummins. Fuel pump actuator 13.

The engine control module ecm has detected that fuel pressure is lower than commanded pressure. These fuel pressure sensors effectively measure fuel pressure in the fuel rail alerting both the evap system and the fuel system to leaks. High pressure fuel pump inlet 11. Seized ceramic plunger compared to how it should look normally.

Last time around 2000 miles ago this sign came i went to peterbilt dealer they changed the fuel filter and scr nox temp sensor. High pressure fuel pump outlet 14. Fuel rail pressure sign. Fault code 559 injector metering rail 1 pressure data valid but below normal operating range moderately severe level.

Besides injector lines this rail also features a return line and pressure relief valve responsible for relieving excessive pressure and a rail pressure sensor that tells the ecm on board computer what pressure is at the rail which can be as high as 30 000 psi and as low as roughly 4 000 psi. High pressure fuel rail supply 15. High pressure fuel pump 12. Then i run around 500 miles this sign came again when i try to climb at moutain.
