Ohm meter or hertz meter. Ohm the outer leads. It should be low 17 to 37 ohms. Anything above or below is bad. Ohm the ground side and the center lead. This will be high ohms. Just a guess but anything above 2000 ohms I would replace it. Using a hertz meter use the ground and center lead. Then use a screwdrivers and sweep it back and forth across the sensor. You should get a reading, if not it's bad.
