Passenger Airbag Sensor Issue?

A month or so ago, I had a friend get into the passenger seat, bounce around as he adjusted it to his comfort, etc. Then or soon after, the seatbelt light started flashing w/ the airbag light on constantly, and the passenger airbag off light (center console) has been on.

I've read some forums and many suggest the sensor has gone bad, as I've otherwise checked the connections and they all look good, but the lights remain. I've also detached/reattached the battery, but nothing changes.

Anything else to check before I get a replacement sensor? And hope that works?

Thanks in advance!

 

Probably just need to be calibrated. I have had to do several for this. It loosed Zero Point Calibration
