2005 Airbag issues
 

We just purchased a used 2005 MPV and the passenger airbag light has been on since we got it (didn't notice in the dealership).
My husband has determined that it is a code B0106/54 airbag error from looking online and there should be a switch that we need to find to turn the Airbag back on. We are unable to locate this switch and are at a loss and do not want to be overcharged if we are able to resolve it ourselves.

Any help would be appreciated.
Thanks

How long ago did you purchase the vehicle from the dealer? Usually a dealer will give you a 30 day warranty on a used vehicle that no longer has factory warranty. I would take it to the dealer to have them fix it, you are dealing with a safety device and in case of a accident you'll want that airbag to work.

B0106 Trouble Code
 

The B0106 should be the MAP Sensor.
