    Need info about MAP sensor

    Can anyone give me info on the MAP sensor from the 07 ecotec. Gm part number 12591290, Bosch part number 261 230 146. I need to know if this is a 1,1.5, or 2 bar sensor. Also does anyone have the pressure VS voltage scale for this sensor?

    Thanks

    I've read elsewhere that it might be 1.5 bar. I knew it was 0-5v, need to know the pressure to voltage mapping.

    Actually bro, you have a MAF sensor as your main air flow meter (as long as you have an 07 setup). If you have a MAP sensor, its not for air metering, its probably for timing retarding and advancing.

    Actually, the engine is in a project car with a standalone ECU. No MAF just MAP.

    Ok, so the question is, which MAP sensor did you get then? From which vehicle?

    Like I said in my original post, it is the stock sensor from the 2007 2.2L out of a Cobalt.
