Cummins isx fuel rail pressure sensor. These fuel pressure sensors effectively measure fuel pressure in the fuel rail alerting both the evap system and the fuel system to leaks. Replacement restores engine performance. High pressure fuel pump 12. This was a close call.

Fuel pressure sensor location 17. 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. Then i run around 500 miles this sign came again when i try to climb at moutain.
