Well, I've got a deleted 2017 ram 2500 Cummins with 27k miles. Ive had zero issues related to the delete and the trucks runs great but Igot a check engine light about 3K miles ago for low coolant as read though my CTS2. Ive heard this is a fairly common problem within the 25-30k mile range. I topped the coolant off, didn’t clear the light. Ordered a new coolant level sensor and installed a couple days ago, still didn’t clear the light and the P2560 was still there. Just checked codes with my cts2 and its showing no codes, which I guess is a good thing as Im hoping the level sensor fixed it, but my check engine light is still on. Does the take a couple cycles to clear?
