Year, make, model and engine? Basically there's an issue with the wireless accelerator pedal not sending signals or the PCM/throttle body not getting signals.

One DT member had a run-away Power Wagon and the problem was in the fly-by-wire TB. Get the truck to the dealer and have it checked before some happens.

its a simple fix if you know about the wiring

Mine came on this morning, turned truck off and restarted.. It was then gone and the truck ran fine.

I wonder if it has anything with the negative temps weve had?

Is there anything I can check before I goto the dealer, mastertech?

Thank you.

Battery &/or alternator should be checked. That is the most common things anyways.
