2011 F250 Service Engine Light - Exhaust too cold
My service engine light came on last week and I couldn't figure out why. The truck was running fine. The truck is still under warranty so I took it in. They diagnosed it and said that the computer diagnostics came back with a trouble code that referenced "engine exhaust too cold." The dealership said they had never seen that trouble code before so they re-flashed the pcm and the trouble code disappeared. This morning, the light came back on. Anyone had this issue before?
