Step 3
1) Turn the ignition switch OFF.
2) Remove the IAP sensor. (

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 the ground -
terminal
2
and
+
terminal to the Vcc terminal
3
.
5) Check the voltage between Vout
4
and ground. Also, check if
voltage reduces when vacuum is applied up to 400 mmHg by
using vacuum pump gauge. (

• If wire and connection are OK, intermittent trou-
ble 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.
NO
If check result is not satisfactory, replace the IAP
sensor with a new one.
