Yes, there is a small fan behind the sensor that pulls cabin air across the sensor. The front 'dust cap' pulls off from the front. If you look in, you should see a small, glass-encased sensor (it may be covered with fuzz & dust - gently clean to remove the dust), and behind that is the fan. The entire assembly has to be removed from the rear of the dash (through the ACC hole when you pull it forward). If it's just accumulated dust etc on the fan, you may be able to gently clean it with a can of 'Dust-Off' or similar compressed air.
