Charles, some make you believe these sensors encounter light-bulb type failures and want to say once they fail, they fail for good. However, this is not true for either:

Case in point I had an intermittent brake light on the truck for a long time. When I got pulled over I told the cop to watch: while my wife stepped on the brake I banged the rear light housing and the brake light came on. He let me go. Eventually I got a new bulb because getting pulled over became old. So believe it or not even light bulbs can fail intermittently. Once the filament makes contact it sort of spot welds a little and the light works....for a while. Vibration undoes the weak connection.

These sensors are known to fail intermittently - mostly due to heat stressing the housing and eventually breaking in the wire to coil contact. What you see is very typical. Good find and I am sure the car will run fine once you replace them.

Best,
Ingo
