    If I'm not mistaken, there are two coolant temp sensors. One in the driver's side head that goes to the gauge on the dash and another near the thermostat housing that is for the computer. The latter should be the one causing the code. If it is new, it is either faulty or you have a broken wire somewhere.

    If you are correct Gary that makes a lot of sense; I changed the wrong sensor. I have cried uncle and handed the truck to a budding mechanic working out of my Brother in Laws shop but will pass this on to them.

    I do love that paper clip trick. I almost want something else to code so I can check it!
