Just checking: you are experienced with soldering electronics, unsoldered the old stepper motor from the circuit board, cleared excess solder, cleaned the pads, then soldered the new one in?

If "yes" then coolant-temperature sensor is working.

The gauge is controlled by the computer, and the computer tells the gauge what to do based on programming and input from the sensor.

forget that I was on my way to work , I accelerated to pass a car and my engine light started flashing, then I ran the code scanner and I had a po300 code come up, my engine light has only flashed in tow mode right before 3 gear and about 3000 rpm, now this is the first time in overdrive
What ever happened with the misfire etc. issue?

the temperature sensor seems to be working normally, on my scanner it stays at 190 degrees which is normal for my truck, the gauge just is reading wrong on dash
