  1. Using Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, connect DVOM (on voltmeter scale) to Green/Orange wire and Blue/White wire at back of MAP sensor connector. Voltage should indicate more than 2.5 volts. Unplug and reconnect MAP sensor vacuum hose. Voltage should indicate less than 2.5 volts. If voltage is not as indicated, replace MAP sensor.
