The engine uses a sensor in the heads. To tell the computer what the actual head temp is(instead of just what the coolant is) If it sets this code either the sensor is having issues or it actually got hot, you should have the engine tested for combustion leaks into the cooling system(we call it "BLOCK LEAK TESTING") if the test turns out ok then have your mechanic look into the sensor.
Hope it helps
