    The one I have here is '16040749', www.gmpartsdirect.com shows this as obsolete.
    The new number is - '12223861', they came from the 89 Turbo T/A's according to that site.

    Cheers,

    I believe the 12223861 is a 3 bar sensor. I googled that number and everything comes up that way.

    I found this nifty page:
    http://www.robietherobot.com/storm/mapsensor.htm

    There's some discussion on LS1tech about using the BARO sensor from a Saturn ION, but the connector doesn't match up, which seems like a needless PITA to me.

    I'm thinking anything from a recent factory S/C 3800 would be plug and play.

    I asked my local dealer for p/n 16040609 and they came back with a new number 12569241 - $40 and some change. Got the original part number from this site: http://www.robietherobot.com/storm/mapsensor.htm
