I have found extremely little info about this sensor on this forum; however, it appear to be the common replacement available these days.

After some further thinking about how to calibrate GM 2 Bar MAP, I have come to the following conclusions:

Sensor voltage vs pressure:
voltage pressure
4.90 14.3
4.84 14.0
4.67 13.0
4.50 12.0
4.33 11.0
4.16 10.0
3.99 9.0
3.82 8.0
3.47 6.0
3.13 4.0
2.79 2.0
2.45 0.0
2.03 -2.4
1.61 -4.9
1.19 -7.4
0.77 -9.9
0.35 -12.3
0.02 -14.3


The "load scaler" is the range of the sensor in Bar. This sensor reads 14.3 PSI at 4.90 volts and -14.3 PSI at 0.02 volts. This is a range of 28.6 PSI or 28.6/14.5 =1.97 Bar.
