I thought I had the correct P/N for the 2 Bar but I just went to order it on GMPartsDirect.com and it's not listed there at all anymore:

2 Bar: 16254539

Odd thing though the weatherpack harness connector was still listed.

Anyway, does anybody have a "good" P/N for the 2 & 3 Bar MAP sensors? I mentioned the 3 because I may be going to that after the 2 and it would be nice to have the P/N handy....

Thanks!

 

2 Bar 16254539
3 Bar 16040749

According to Doc.

 

The 2 Bar # 16254539 still is not good, there must be a new one now...

Also the new 3 Bar P/N is 12223861

Both use the same harness connector 15305891

Ouch... BW

 

That's the new 3 Bar but I still need the new P/N for the 2 Bar which I'm sure others here will need sooner or later also...

 

Auto Zombie and Disadvance both have 2 Bar sensors. Search 1990 Sunbird Turbo.

No luck with the GM numbers either. BW

EDIT:

Cool.... MAP sensor catalog with OEM numbers..

New GM 2-Bar MAP #12569241 or ACDelco #213-1520

I know these are correct #s as I ordered this part recently.

Hope this helps!
