Paccar MX13 Intermittent No Power - No Throttle video by Dr. Paccar

Dr, Paccar returns with another weird Paccar MX13 problem, On a 2018 KW the driver complaint is power loss or no throttle intermittently. There seems to be no check engine light that alerts the driver to any type of codes. The first step was to replace both the fuel filter on the engine and the fuel separator. This was NO help, Since it was under a 2 year warranty the truck was sent to a local Kenworth dealer. Two days later they condemned the MAP sensor and replaced it. However the truck was sent back out and the driver had the same issues. So I looked at the truck myself. After a little experimenting it was not a engine issue but a ABS anti-lock brake issue. Watch the video to learn how and why.
