Fuel rail pressure sign.

Cummins isx fuel rail pressure sensor.

Then i run around 500 miles this sign came again when i try to climb at moutain. Fuel pressure sensor location 17. Replacement restores engine performance. The engine control module ecm has detected that fuel pressure is lower than commanded pressure.

2013 peterbelt 386 isx 15 cummins. This was a close call. Pressure side fuel filter inlet 9. Pressure side fuel filter 5 micron 10.

High pressure fuel pump 12. High pressure fuel pump inlet 11. Fuel pump actuator 13. High pressure fuel pump outlet 14.

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. 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 rail supply 15. Last time around 2000 miles ago this sign came i went to peterbilt dealer they changed the fuel filter and scr nox temp sensor.
