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 in series (1) (check that
total - voltage is 4.5 – 5.0 V) and connect (–) terminal to
ground - terminal “C” and (+) terminal to the VCC
terminal “D”.
5) Check the voltage between Vout terminal “E” and
ground.
Also, check if voltage reduces when vacuum is applied
up to 400 mmHg by using vacuum pump gauge.

(A): 09917–47011 (Vacuum pump gauge)
(B): 09900–25008 (Multi-circuit tester set)

Voltage (
)
Is the voltage OK?
• R, P/B or B/Br wire
open or shorted to
ground, or poor “5”,
“3” or “12” connection
(#2).
• R, G/B or B/Br wire
open or shorted to
ground, or poor “5”,
“22” or “12”
connection (#1).
• 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.
If check result is not
satisfactory, replace the
IAP sensor with a new
one.
