I'm not sure about years prior to 1998 but I can tell you that from 1998 - 2002 there are NO airbag sensors in the front bumper assembly. All the sensors are contained in the ADU which is located under the front console. There are pendulum type sensors which sense impact.

But again, that's for 1998 and newer. I don't know about prior years and if you DO run into sensors in the front bumper I would leave them alone.

1998 Sportage - Gone.
2004 Honda Civic Coupe.
2007 Suzuki Grand Vitara - She got it.
