have a 2008 F-150 driving down the road at 65-70 mph and the ABS light comes on. When i stop and turn the truck off it goes off until later ? Any help ?

 

i had this issue on my 07... abs light would be off until it tried engaging then the light would stay on until you turn the truck off.

i was getting a code for right front sensor.. i took the abs sensors out of the hubs (2 little screws) and sprayed brake cleaner on them.. havent seen an abs light since!
