Manifold Pressure/Vacuum Sensor: Testing and Inspection
Manifold Absolute Pressure (MAP) Sensor Inspection
1. Disconnect connector from MAP sensor.
2. Remove MAP sensor.
3. Arrange 3 new 1.5 V batteries (2) in series (check that total voltage is 4.5 - 5.0 V) and connect its positive terminal to "VIN" terminal of sensor
and negative terminal to "Ground" terminal. Then check voltage between "Vout" and "Ground". Also, check if voltage reduces when vacuum is
applied up to 400 mmHg by using vacuum pump (3).
If check result is not satisfactory, replace MAP sensor (1).
Output voltage (When input voltage is 4.5 - 5.5 V, ambient temp. 20 - 30 degrees C, 68 - 86 degrees F)
4. Install MAP sensor (1) securely.
5. Connect MAP sensor (1) connector securely.
