passage for clog. Clean if clogged.
2) Check sensor O-ring (1) for damage and deterioration.
Replace as necessary.
3) Arrange 3 new 1.5 V batteries (2) in series and connect its
positive terminal to “Vin” terminal of MAP sensor (1) and
negative terminal to “Ground” terminal. Then check voltage
between “Vout” and “Ground”.
Also, check if voltage reduces when vacuum is slowly
applied up to 400 mmHg by using vacuum pump (3).
If check result is not satisfactory, replace MAP sensor.
MAP sensor output voltage (When sensor input voltage is 4.5
– 5.5 V, ambient temp. 20 – 30°C, 68 – 86°F)
