I have a 2010 Prostar with a Cummins ISX engine. I've been having an issue where if I'm driving with a load, as I increase my speed and get up between 50-60 mph, my yellow engine warning light comes on. As I continue to drive and increase the speed between 65-70, the red light comes on. I have to pull over and shut the truck off. Once restarted, the lights are gone. Then everything happens all over again.

I took the truck to the shop to have it scanned and I had 52 faults for the crankcase pressure sensor. I changed the sensor and the same thing keeps happening. Back in January I had these similar issues and after a scanning was done I changed the filter. This was the first time I've changed the filter since I've had the truck and it's going on 3 years. When I first put the new filter in the truck ran mostly issue free. Besides an occasional yellow light popping on then going back off by itself. I never had to stop the engine due to the red light until a couple of days ago. I checked the filter today and it looks pretty dirty again. The filter has a greyish color. Before it was closer to black.

Does anybody have any clue as to what can be happening? It has to be something related to the crankcase sensor and filter. What could be causing it to trip?? Why is the filter dirty so soon? If anyone can help with any info I'd greatly appreciate it. Btw, the truck has 719k miles.

Thanks

so you severely neglect your engine and expect it to run ok? crank case filter shoulb be replaced every 80k miles max on a new truck, one with wear and blow-by it is more often than that.
