Can anybody confirm that GM map sensor #12580698 will report up to 260kPa?

Some posts say it's a 2.5bar 260kPa sensor.

Some posts say it's a 2.0bar 210kPa sensor.

TIA.

Yea I see what you mean...

12580698 It's actually the BARO sensor for the [04 Saturn] Redline and the 05 cobalt. Correct part number though. 2 BAR, same physical package at the stock 1 BAR sensor. The MAP sensor on the ION/cobalt is 2.5 BAR w/ built in temp sensor. The packaging and connector is different however.

Hmmm, Maybe with a 5 volt reference source and a 50PSI air tank with a good digital tire gauge you can plot the output curve vs. PSI...

It's a 2bar baro sensor from the ION... least that's what I was told on tech before I bought one (in the same link posted above).

You guys are right!


Talked to a Delphi engineer.

20-200kPa

Only a 2 bar

This is a BAP sensor for the SS Cobalt/ Saturn Ion....not the map sensor...can be used as a map sensor (I'm using one now), but it is not 2.5 bar.

The Cobalt SS also uses another combo MAP/IAT sensor that is 2.5bar, hence the confusion.
