INTAKE-AIR SYSTEM
2. Disconnect the IAC valve connector.
3. Measure the resistance between the IAC valve terminals using an ohmmeter.
• If not as specified, replace the IAC valve. (See F10 INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)
• If as specified but the Operation Test is failed, carry out the Circuit Open/Short Inspection.
Specification
Circuit Open/Short Inspection
1. Disconnect the PCM connector. (See F43 PCM
REMOVAL/INSTALLATION.)
2. Inspect the following wiring harnesses for open or
short (continuity check).
Open circuit
• If there is no continuity, the circuit is open. Repair
or replace the harness.
 IAC valve terminal A (harness-side) and PCM
terminal 4G
 IAC valve terminal B (harness-side) and PCM
terminal 4J
Short circuit
• If there is continuity, the circuit is shorted. Repair or replace the harness.
 IAC valve terminal A (harness-side) and power supply
 IAC valve terminal A (harness-side) and GND
 IAC valve terminal B (harness-side) and power supply
 IAC valve terminal B (harness-side) and GND

VARIABLE INTAKE-AIR SYSTEM (VIS) SHUTTER VALVE ACTUATOR INSPECTION (L3)
A6E391013000W05
1. Remove the air hose. (See F10 INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)
2. Disconnect the vacuum hose from the VIS shutter
valve actuator.
3. Connect a vacuum pump to the VIS shutter valve
actuator.
4. Apply vacuum and verify that the rod moves.
• If the rod dose not move, replace the intake
manifold.

VARIABLE INTAKE-AIR SYSTEM (VIS) CONTROL SOLENOID VALVE INSPECTION (L3)
A6E391013000W06
1. Remove the VIS control solenoid valve. (See F10 INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)
2. Inspect airflow between the ports under the
following conditions.
• If not as specified, replace the VIS control
solenoid valve.
• If as specified, carry out the Circuit Open/
Short Inspection.
