forddieseldoctor Posted October 9, 2023 Share Posted October 9, 2023 I picked up a 2019 F350 with a 6.7. My question is does the engine hour meter keep running if the truck is sitting koeo or does it manage to know that the engine is not running? I know that the trip meter timers keep running and I noticed that when I had the key on for a half hour Friday night while I was tinkering with some accessories that I installed the fuel mileage history screen completely cleared out all the bars and made everything zero.

Lonnie Olsen Posted October 27, 2023 Share Posted October 27, 2023 From what i can find the answer is no. Koeo will not increase engine hours. It looks like engine idle hours are based off engine rpm signal and engine hours use speed signal, truck has to be moving for that one. 1 Quote Link to comment Share on other sites More sharing options...
