Today the check engine light came on and the code on the dash is P 0514. Can someone tell me what this means? Its on a o4.5. Thanks

 

P0514 Battery Temperature Sensor Performance / Rationality

Seen a few posts on this, but don't really remember if there was a real reason or just one of those that happen occasionally. Maybe someone with experience with it will chip in.

 

It's a battery temperature rationality code. There have been lots of these codes set. There is a flash out to take care of it.

 

Thanks, should i worry about it? I cant get it to the dealer any time soon.

 

No worries, get there when you can, your truck won't stop.

 

My garage is not heated but I do have 4" of insulation in the attic. Inside the garage can get 30* difference if a cold front comes thru at night. Mine seems to come on 0514 (Battery temp ) or 0071 (air temp) whenever a big change in temperature. CEL came on twice last spring and only once this fall.
It goes away in a day or two. I just got a Autoscanner this fall and cleared it myself.
