Variable Intake Air Solenoid Valve Inspection

VARIABLE INTAKE AIR SOLENOID VALVE INSPECTION [L3]

1. Remove the variable intake air solenoid valve.
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".






Circuit Open/Short Inspection
1. Disconnect the PCM connector.
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 A and PCM terminal 2J
- Variable intake air solenoid valve terminal B and main relay terminal C

Short Circuit
- 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
