1A-42 Engine General Information and Diagnosis:
Step
4 1) Turn the ignition switch OFF.
2) Remove the IAP sensor. Refer to "IAP Sensor Removal
and Installation" in Section 1C (Page 1C-2).
3) Connect the vacuum pump gauge to the vacuum port of
the IAP sensor.
4) Arrange 3 new 1.5 V batteries (1) in series (check that
total voltage is 4.5 – 5.0 V) and connect (–) terminal to
the ground terminal "B" and (+) terminal to the VCC
terminal "A".
5) Check the voltage between Vout terminal "C" and
ground. Also, check if voltage reduces when vacuum is
applied by using vacuum pump gauge.

• G/B, R or B/Br wire
open or shorted to
ground, or poor "19",

connection.
• If wire and
connection are OK,
intermittent trouble or
faulty ECM.
• Recheck each
terminal and wire
harness for open
circuit and poor
connection.
• Replace the ECM
with a known good
one, and inspect it
again. Refer to "ECM
