So first things first the car is not over heating, I recently changed the ect sensor and for some reason the gauge on the dash has been stuck on high. Which makes no sense because coolant is flowing, I tried unplugging the battery for one hour and still nothing the gauge is just stuck all the way up and i cant figure out how to make it go down. please let me know if anyone has heard of this. and let me know if any more info is needed thanks!
