The temperature varies, it wont always throw that code. Its because of your camshaft sensor ( plug coming from your distributor) clean it with some electrical contact spray. See if it helps. If your not having any performance issues because of it, i wouldnt mess with it, but if it bothers you thst bad, then to change the sensor you have to change the distributor
