engine light but no faults or warnings

If the engine light is on it has a fault logged. Need someone to get hooked up with Davie and see printouts.

 

The light can mean a software update is available/needed and it can mean you have a problem. KWs have a bug "STOP ENGINE NOW" and the smaller engine-looking icon I always called the check engine light. I think the small icon is the Engine Information Light. It serves multiple functions. MY KW had either a satellite or cellphone link built-in that can trigger the EIL and send info about your driving and engine parameters to the boss and the factory/dealership.

 

I just had something similar happen with my Paccar MX13. Peterbilt told me it's a it's has to do with the Air Intake. Originally, at a local mechanic I go to had a reas that it had could be the Turbo Actuator. Peterbilt had a more accurate reading on the problem. My truck has around 187,645 mi on the motor with 4125 hrs. I rarely idle the truck unless when at the border more than 1 hr I usually shut it down after 15 minutes of idling. I change the oil between 15k to 18k mi's . Yours is 2019 so, it's probably has a lot more miles but I'm finding that Paccars can sit to long or else something wants to start seizing up.
