2007 nissan maxima airbag code b1019?

I have a 2007 nissan maxima with 104,000 miles. My airbag light is on and the code reads b1019 weight assist sen unit fail. The only thing I notice was that when someone is sitting on the passenger seat the airbag stays off. I went as fair as replacing the seat and still nothing. Dont know what else I can check.

    Sensor is not getting reference voltage or ground, sensor signal wire is bad, sensor is bad, sensor is disconnected.  Suspect a bad wire.  You can put some weight on the seat and fix your problem. Get the next owner to fix it. Good luck.
