[QUOTE="audioatg, post: 7292530, member: 570057"] So you have tested the sensor. How about the gauge and wiring. And are you sure you have the right sensor. Some of them GM truck have two sensors. One for the temp gauge other is for the computer. What motor is in it. You have the check the wiring and gauge side now. Although I would still replace that sensor they go all the time. Not doughting your diag skills. Now trying to remember this. But if you discount it with key on engine off the gauge should full sweep to highest reading. Then if you jump the two wires with key on engine off still the gauge should full sweep back. If it does not you have a problem in the wiring and or gauge. Im pretty sure its a two wire setup for the gauge. One should be the power(sense wire) and other ground. [/QUOTE]
