if it's all the way hot, the wire may be disconnected or shorted to ground, I forget which one makes the temp go high. Try disconnecting the sensor and see what the guage reads....it's based on resitence to ground, and I think if it's disconnected the gauge should read low. If you disconnect and the gauge does not drop, the wire may be "pinched" and grounded.....
