1A-35 Engine General Information and Diagnosis:
4 1) Remove the IAP sensor. Refer to “IAP Sensor Removal
and Installation in Section 1C (Page 1C-2)”.
2) Connect the vacuum pump gauge to the vacuum port of
the IAP sensor.
3) Arrange 3 new 1.5 V batteries in series (1) (check that
total - voltage is 4.5 – 5.0 V) and connect (–) terminal to
ground - terminal “A” and (+) terminal to the VCC
terminal “B”.
4) Check the voltage between Vout terminal “C” and
ground.
Also, check if voltage reduces when vacuum is applied
up to 400 mmHg by using vacuum pump gauge.
Special tool
(A): 09917–47011 (Vacuum pump gauge set)
(B): 09900–25008 (Multi circuit tester set)

Voltage ( )
Is the voltage OK?
Replace the ECM with a
new one. Refer to “ECM
Removal and
Installation in Section
1C (Page 1C-1)”.
If check result is not
satisfactory, replace the
IAP sensor with a new
one.
