Connect the test harness lo the ECM (page 5-8).
Measure the voltage at the test harness terminals (page 5-9).
The MAP sensor output voltage (above) is measured under the standard atmosphere (1 atm = 1,030 hPa). The MAP sensor output voltage is affected by the distance above sea level, because the output voltage is changed by atmosphere.
Check the sea level measurement and be sure that the measured voltage falls within the specified value.
