There are sensors in the valve stems of the tires. Chances are (if the pressure is good) one of the sensors is bad. You can have the computer scanned at a nationally recognized parts store to determine where the problem is coming from. Most of these places will do it for free. As far as the fuel gauge, does it stay still when you are at a stop?
