I have a 2000 f150. While driving the speedometer drops to zero. Temperature gauge drops to cold. RPM stay the same. OD light flashes. And oil light comes on. Eventually when I slow down the speedometer goes back up and truck takes off. Now check engine light is on and I've changed the sensor several time for the code I keep getting.

 

Try a battery reset. The info is in your owners manual.

 

So you think that will solve the problem speedometer and other problems. With a reset of the battery. Or will it just clear the code?

 

Try it and find out. Costs nuthin!

 

What is the code you refer to?

 

The code I keep getting is the crank shaft sensor.
