Front airbag sensor replacement

I guessed,,, sorta,,, looking up from the bottom at the 10 mm bolt head,, I noticed a slight cracking in the black plastic,,, when I took it down it was worse on the top side of sensor. water gets trapped in the bore area of the mounting hole,,, like a cup filled with water.. then it can freeze and split the sensor. I filled my new one with rtv.

I then ordered the other one and did the same,, it was also cracked but still registering. dorman 590-206

I went ahead and ordered the Dorman sensor and replace it last weekend. I did the same and dropped the skid plate to see/feel which one may be bulging. Sure enough, my passenger side sensor was visibly swollen. After replacing it, my airbag system is back to normal. I figured it was a 50/50 chance on what sensor was bad, so an educated guess served me well in this case. :)

Thanks for all the helpful info. The cheap Dorman sensor for $60 worked just fine for me. I purchased the Autel AL619 code scanner for $100 and it read my chevy silverado just fine. You just have to know that there is a separate ICON on the screen for reading airbag codes. It told me right front sensor so I went right to it. Replaced it in 15m. Also, my sensor was clearly cracked open just like the pic someone posted above. So I guess you could avoid the scanner purchase just by inspecting the sensor. I like the scanner and already used it to read another code.

New member here digging up an older thread.
Among the many things currently causing problems with my truck. The air bag light is "on" . Got the service air bag message popping up also. Replaced both sensors up front (they were obviously bad, split and corrosion falling out). Surprise Surprise the light and message is still there. So after reading down through this post I'm thinking the module under the seat. The post about the recall just talked about removing the padding at no cost so it don't short out the module. Will they replace the module at no cost if it is already shorted? '09 Chevy Silverado 1500 rolling around the Ohio rust belt.

I think you have to get it reset by GM if I remember correctly
