I had airbag code 44 before...which is the right side sensor code. I found, in my case, it was because of the ground wire for that sensor....that particular (right side one) grounds out on the little metal cross-member behind the headlight. Anyway, in your case i'd say follow the ground wire from the sensor down to where ever it goes and clean up the ground and make sure that there is good metal to metal contact and it's tight....if the code doesn't go away still, i've read that people have removed the actual sensor and cleaned up where it attaches to the body....but i'd be careful there...don't know what it takes to trigger the airbags.
BTW, the sensor on my car just looked like a small black box.
Edit: Tony was a little quicker.
