⁽¹⁾	MAP sensor output voltage is tested with three 1.5-volt batteries connected in series (output 4.5-5.0 volts). Positive lead of batteries is connected to "Vin" terminal. Negative lead of batteries is connected to "Ground" terminal. Check output voltage between "Vout" and "Ground" terminals.

⁽²⁾	Voltage should reduce when up to 15 in. Hg of vacuum is applied to MAP sensor.

CAUTION: Blowing compressed air through mass airflow sensor will damage it.
