MAP Sensor Part Numbers

[Walter Sherwin]

You'll need a few part numbers in order to easily procure these MAP sensors
through a GM dealer.  These numbers, and a bunch of other really neat stuff,
are buried in the archives associated with these lists.  If you ever find
yourself short on reading material one night, pull-up a chair and peruse the
archives.  Interesting reading!

For a 3 Bar sensor (reads from below atmospheric to roughly 30 psig boost)
use P/N 16040749.  For a 2 Bar sensor (reads from below atmospheric to
roughly 15 psig boost) use P/N 16009886.  For a 1 Bar sensor (reads from
below atmospheric to roughly 0 psig boost)  take your pick from any of the
non boosted GM engines, as they are all pretty much similar.

Merry Christmas!





>>  Does anyone know which GM map sensor I would need to run a Haltech, that
>>  would be able to read up to around 30psi? Is one bar up to 14.7 PSI, or
is
>>  it for naturaly aspirated cars?  I'm confused..Thanks in advance.

>The One bar GM MAP reads the pressures "BELOW" atmospheric.
>  (used in naturally asperated GM MAP systems)
>The two bar MAP will allow measurement of that, plus 16psi of boost..
>    (MAP sensor used in 87-90 TurboSunbird & 91 Syclone)
>The three bar piece will allow detection of up to 30 psi of boost.
>    (Used to run the boost gauge in the 89 Anniverary 3.8 Turbo TA)
