I have a couple trucks throwing flash codes 42 and 56. They haven't had a new ECM installed, had the head removed etc. The batteries in them were taken out for the winter and recently put back in. Anybody have any ideas or think I should send them out to be recalibrated? I checked the ecm connector, crank and cam sensors, and they check out. Ones in a 2004 Western Star 4900, 300,000 km. Thankss!!
