Variable Induction Control Solenoid: Testing and Inspection

VARIABLE INTAKE AIR SOLENOID VALVE INSPECTION [LF]

NOTE: Perform the following inspection only when directed.

Airflow Inspection

1. Remove the battery cover
2. Disconnect the negative battery cable.
3. Remove the variable intake air solenoid valve.







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.




2. Inspect the 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
