Temp on the display showed 0 to 1* anyone have more information on this code? Truck seemed to act normal for the cold weather, didn't notice any driveability issues.
Either your MAP sensor or your exhaust backpressure sensor has gone bad. Probably the EBP, odds are. I don't have a DashDaq, but it seems like you could view the output from both of them when you key on, before you start the truck. On what will be a cold start, one of them will probably be different than standard atmospheric pressure where you live. That's the bad one.
