I just joined this site for info on my 2006 Ford F-250 6.0 Diesel. Need answer on speedometer problem. Reads 70mph when truck is off and when running it thinks 70 is the new zero mark. Also I'm not a computer geek like my son so it takes me a while to figure out the site and what to do. I'm just getting use to the site. It's a great place for Ford info. Nice to be here, Pete.

 

Welcome, Pete. Good Luck.

 

failed speedo head. there is a great 6.0 section here. this may get moved there.
