6E2-40 ENGINE AND EMISSION CONTROL SYSTEM (SEQUENTIAL MULTIPORT FUEL INJECTION FOR H27 ENGINE)
INSPECTION
1) Check sensor O-ring (1) for damage and deterioration.
Replace as necessary.
2) 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 manifold absolute
pressure sensor.
MAP sensor output voltage (Vin voltage 4.5 – 5.5 V, ambi-
ent temp. 20 – 30°C (68 – 86°F))
CAUTION:
As connection to wrong terminal will cause damage to
manifold absolute pressure sensor, make absolutely sure
to connect properly as shown in the figure.
