Yes, a new airbag sensor is required. Like an airbag, they are only good for a single use.

There is but one airbag sensor and it controls both airbags. You'll find it underneath the front of the console, in front of the shifter.

That was just answered above, under the very front of the console in front of the shifter. No worries about our airbags going off from even really rocky/bumpy trails. The only thing that will set them off is a major forward impact at a speed that would cause serious injury if the airbags did not go off. I'm talking 20-25 mph. No amount of up-down jolts will set them off... only a major forward impact will do it.

Oh sorry I thought there was a separate impact sensor from the module.

That module's sole one-time job is to be the impact sensor. It has a steel ball inside positioned at the opening of a forward facing tapered slot. A strong enough forward impact will drive the steel ball forward into that tapered slot to make the electrical connection used to trigger the airbags.

I'm not knocking you at all, just asking because I don't fully understand how that sensor works. How can it only be used once? Does the ball not come back out of the tapered slot once it goes in and makes the electrical connection?

Exactly, it's a one-time device... just like the airbags it controls. .
