The temperature sensor must be shorting out to ground. Try pulling the wire off the sensor, and if the gauge drops to zero, it's the sensor. If you short the wire to ground, the gauge should show full scale, so if the gauge still shows full scale with it pulled and not shorted to ground, then the wire is shorted to ground somewhere on its way to the gauge.
