AIR CLEANER ELEMENT INSPECTION [L3]
- Remove the air cleaner element. (See «INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L3]»(ref-244570-S29535323642006092500000) ).
- Verify that the air cleaner element surface is free of dirt. If there is dirt, use an air gun or similar tool to clean the element. If the replacement time limit has passed, replace the element.

- Remove the air cleaner case. (See «INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L3]»(ref-244570-S29535323642006092500000) ).
- Disconnect the vacuum hose from the VAD shutter valve actuator.
- Connect a vacuum pump to the VAD shutter valve actuator.
- Apply vacuum and verify that the rod moves. If the rod does not move, replace the air cleaner.

Scheme 138
- Disconnect the PCM connector. (See «PCM REMOVAL/INSTALLATION [L3]»(ref-244558-S14017244512006092500000) ).
- Inspect the following wiring harness for open or short circuit (continuity check). (Scheme 138): Identifying VAD Control Solenoid Valve Connector Terminals

- If there is no continuity, there is an open circuit. Repair or replace the harness. VAD control solenoid valve terminal B and PCM terminal 1K VAD control solenoid valve terminal A and main relay terminal C (Scheme 139): PCM Connector Terminal Identification
THROTTLE ACTUATOR INSPECTION [L3]
Note. Perform the following inspection only when directed.
Resistance Inspection
- Disconnect the negative battery cable.
- Disconnect the throttle body connector.
- Measure the resistance between the throttle actuator terminals using an ohmmeter. If not as specified, replace the throttle body. (See «INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L3]»(ref-244570-S29535323642006092500000) ). If as specified, carry out the "Circuit Open/Short Inspection".
