There is no senor on the expansion tank. Check coolant level in the radiator. Or the sensor may be in the top off the thermostsat housing. Check the senor has power connected to it. If all correct remove senor and fill with coolant, it my have gatherd an air lock under the senor.

Could be a resticted radiator, or a thermostat that is stuck closed. A BAD HEAD OR HEAD GASKET WILL NOT HOWEVER, ALWAYS MIX OIL AND COOLANT. The best thing to do is purchase a block tester. It's a cheap(around thirty dollars)way to rule out a breached head gasket. Most parts stores have these. Follow the enclosed directions. If you can rule these combustion breeches out, then replace the thermostat, and if that fails, my next guess would be a restricted radiator. I am assuming that your coolant fan is operating properly.
