Manifold Absolute Pressure (Map) Sensor

1. Connect vacuum/pressure gauge to intake manifold. Turn ignition on. On 9-3 models, backprobing MAP sensor connector, measure voltage between MAP sensor terminals "A" and "D" with pressure and vacuum applied. See COMPONENT LOCATIONS  . See Fig 1 . See MANIFOLD ABSOLUTE PRESSURE/CHARGE AIR PRESSURE SENSOR VOLTAGES  table. Replace sensor if voltage is not as specified.
2. On 9-5 models, measure voltage between manifold absolute pressure sensor terminals "A" and "B". See Fig 1 . Replace sensor if voltage is not as specified.
