Check the oil lines in the passenger side wheel well, there is a thermostat there. If the return line is cold when it is reading high on the gauge, that may be an issue with it's operation.

If the gauge is reading high and both are hot, it may be an issue with your fan (if you have one) on the oil cooler in the front fender.
