Manifold Pressure/Vacuum Sensor: Testing and Inspection
MAP Sensor Individual Check
1. Disconnect coupler from MAP sensor.
2. Remove MAP sensor.
3. Arrange 3 new 1.5 V batteries 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.
