Where is the crash sensor located?

Airbag sensors usually are located at the front of most of today’s American made automobiles. They are placed purposefully in the known impact zones of a vehicle. This way when a crash occurs, the sensors can signal the airbag to deploy nearly instantaneously.

How can you tell if a crash sensor is bad?
