Temp Gauge running hot

[Thexfactord22]

I have a 03 Grand Prix Gt, my temperature gauge is always running hot when the car is not actually heating up. I hooked the car up to a computer/scanner and the scanner reads 210-219 but the gauge is all the way up at 235. I just replaced the temp sensor and i dont seem to understand why this is happening.

Also could the sensor be the problem, if so how is the scanner getting the right reading if the sensor is bad?

hey fellow southfielder. i have seen others do this also...maybe sensor again. could be the guage i guess. i dunno the year ....

The year is 2003 i just got a new sensor, and im putting in in as soon as the car cools down. Ill let u guys know what happens.

Probably the gauge its self.

I have gotten sensors that are off. there is 2 sides to the sensor. One side is for your pcm and the other side works your gauge.

Alright, i replaced the sensor and the gauge works perfectly now. I just hope it stays that way.
