Where is the MAP sensor?

In my girlfriend's 90' TBI Camaro, an SES code was tripped and it has to do with the MAP sensor. I looked in the manual and I could not find it anywhere. Any help? Thanks.

its a thin box about 1" x 3" black box. it should be located around your intake somewhere. On my 3.4L (not saying its the same by anymeans) it's mounted on the right side (drivers side) of the intake plenum.. it has a vaccum line or two that goes into the bottom of it. i wish i could help ya with the location, but thats the best description i can think of what it looks like.

Yeah, i know what mine looks like, it is in plain site right next to the throttle body, I can't seem to find this one though.
