need help!!
 

i was driving down the road today and out of the blew i hear a ding and look and the instrument panel, the park brake light and the ABS light start flashing and my speedo kept jumping up and down, and then it would go away. called a service tech and he said that it was more than likely the rear wheel speed sensor. does this make sense. also a couple of times the water in fuel light would flash and the truck would chug, then quit. any help would be great.

I would say thatd be a pretty good place to start sure sounds like it anyhow
