93 throttle positioning sensor problems

I have installed 2 new TPS's on my 1993 Dodge diesel pickup and they keep going out in about 1/2 hour of use. Then the truck will not go into overdrive. Any ideas what could be wrong?

Ditch the TPS return it for your $200 dollars. Get a cord with 3 wires and a potentiometer from radio shack for 5 dollars and wire it to the wire that plugs into the tps.

all the TPS is an extremely expansive potentiometer in a factory package.
i agree with "Left" You need to find out why its burning out. I would be willing to bet the computer is ether over powering it or you have a break in the wire that is causing an over power condition
