1997 850GLT Need help identifying a sensor

Post by jjmtjordan »

Sensor Volvo 850 engine.JPG
My daughter was practicing for her driving exam the other day when I heard something fall out of the engine bay. I found a washer and a cover that went to the sensor that is circled in the picture. Anyone know what this is called and/or does?

Thanks for your help.

She must have also been learning the quirks of locking, and un-locking a Volvo 850 Series.

What you heard was the last vibration of that alarm.
Alarm horn disabled by the nut missing from the center post.
