I want to make sure I have a 3-bar map

[AlaskaTy]

I ordered it a year ago and had it put in when I got an engine installed. But when I took it out to go to a 2-bar the part # on the back didn't match what sytyauthority had to say. The back of my "3-bar" map sensor has a white sticker on it that says:
050903 1544
Part 12223861
Lot G1UJD2

I ran the part # through gmpartsdirect and it found no matches.

Run the part number on google. It shows up as a 3 bar.

or check the inside of it. If it's black it's a 3 bar.

Stock boost gauge will read 0 vacuum with the 2-bar. It will be less with the 3-bar.

Yes Alaska ty, that is the correct map sensor, the old number on syty authority has been superseded by gm to the new number you have now. I bought one and went throught the same thing. Larry.
