You cannot measure its resistance accurately, since there is a large series resistance with the output, and the wear only occurs under the contacts. A good one or bad one will measure about the same on a resistance scale. You can SEE the wear if you remove the pot, and you could measure the erratic voltage probably if you disconnect the EHA plug. However, when you remove the pot, the wiper stays captive to the airflow meter, so the center terminal of the pot will measure open circuit. Still, inspection is your best bet, and replacement.
