In my opinion, the plug pins are getting loose inside the pcb soldering pads, so they have to be re-soldered. Following the circuit diagrams posted by Christine, You may confirm which sensor creates the problem.
I am having a similar issue, and from what I've tested the electrical connection, the air bag will deploy, but the system indicates a stand-by current problem.

 

That makes total sense, as I've been getting a random airbag light in the dash every now and then. Thanks!!
