View the voltage with MeS.
Standard: 2.7 - 3.1 V
The MAP sensor output voltage (above) is measured
under the standard atmosphere (1 aim
=
1,0 13 hPa).
The MAP sensor output voltage is affected by the
distance above sea level , because the output voltage is
changed by atmospheric pressure.
Check the altitude and be sure that the measured
vol tage falls within the specified value.
