Use an ohmmeter to test the resistance; sb about 1000 ohms (if I remember correctly) plus or minus 150 ohms.

It's a magnetic sensor w/ no electronic parts. They're pretty reliable and usually don't fail unless the unit is mechanically damaged.

One last point; If it was "bad", the car wouldn't run!
