Engine Number 46739547, this is the only fault, the code clears and returns immediately, engine speed is restricted, pressure tubes verified clean and leak free and properly routed, first time for DPF cleaning that I am aware of, no real history of engine oil or coolant consumption. Truck only has 125,000 miles, not a road truck, it is a Kenworth service body used locally for hauling equipment and supplies to job-sites.
