Scheme 143

Scheme 144

1. Remove the variable intake air solenoid valve. (See «INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L3]»(ref-244332-S08851886592006092100000) ).
2. 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".

Scheme 145

1. Disconnect the PCM connector. (See «PCM REMOVAL/INSTALLATION [L3]»(ref-244330-S07461751642006092100000) ).
2. Inspect the following wiring harness for open or short (continuity check).

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

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

Scheme 146

1. Remove the air hose. (See «INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L3]»(ref-244332-S08851886592006092100000) ).
2. Disconnect the vacuum hose from the variable intake air shutter valve actuator.
3. Connect a vacuum pump to the variable intake air shutter valve actuator.
