2008 cm871.Just got a check engine light come on at idle but hasnt come on at all while driving.dont know code but screen says fuel delivery pressure.could it be something simple like fuel pressure sensor
Cummins is funny in this department when it comes to displaying what the fault is. I bet if you looked up the actual code it will tell you to check/replace the exhaust pressure sensor and check the tubing to it.
