A few weeks ago my 2012 F150 speedometer started not coming up to 0 when I crank it and reading about 15 MPH slower than my GPS speed. I’ve run the engineering mode gauge sweep and both the tachometer and the speedometer twitch for a few seconds before doing the sweep. The speedometer stops 15 MPH short of a full sweep.
Has anybody had a problem like this or know what I need to do to fix it? Thanks
