If temperature gauge indicates hot replace coolant temperature sensor. If temperature gauge does not indicate hot go to next step. Check RedWhite Wire For Short To Ground - Turn ignition off.
Disconnect instrument cluster harness connector C237. Measure resistance between instrument cluster harness connector C237 pin No. 9 RedWhite wire.
When the temp gauge is on hot and I rev the engine temp gauge needle goes down a little bit. Fan switches on on Hot reading then turns off when the needle goes down a bit still the engine is not smoking nor does it feel really hot. Its just a normal temperature as far as I can tell.

Engine temperature gauge is spiking to the maximum range for short periods of time 2-3mins and then quickly drops back to normal 50 of gauge. No engine warning lights. Occurs about every other day driving in stop and go traffic 50 mph max usually to work in the morning so the outside temp is 70s.
