Note
• Perform the following inspection only when directed.

Airflow Inspection

1. Remove the battery cover.

2. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [L8, LF].)

3. Remove the variable intake air solenoid valve. (See VARIABLE INTAKE AIR SOLENOID VALVE REMOVAL/INSTALLATION [L8, LF].)

4. Inspect airflow between the ports under the following conditions.

• If not as specified, replace the variable intake air solenoid valve.
• If as specified, carry out the "Circuit Open/Short Inspection".

Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [L8, LF].)

2. Inspect the following wiring harness for open or short (continuity check).

Open circuit

• If there is no continuity, the circuit is open. Repair or replace the wiring harness.
- Variable intake air solenoid valve terminal B and PCM terminal 2J
- Variable intake air solenoid valve terminal A and main relay

Short circuit

• If there is continuity, the circuit is shorted. Repair or replace the wiring harness.
- Variable intake air solenoid valve terminal B and power supply
- Variable intake air solenoid valve terminal B and body ground
- Variable intake air solenoid valve terminal A and body ground
