Variable Induction Control Solenoid: Testing and Inspection

VARIABLE DYNAMIC EFFECT INTAKE-AIR (VDI) SOLENOID VALVE INSPECTION

1. Disconnect the negative battery cable.
2. Remove the VDI solenoid valve. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)







3. Inspect for airflow with the steps in the table.
- If it is normal, inspect related wiring harnesses.
- If there is any malfunction, replace the VDI solenoid valve. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)

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 harness.
- VDI solenoid valve terminal B (harness-side) and PCM terminal 1W
- VDI solenoid valve terminal A (harness-side) and main relay terminal C (harness-side)

Short circuit
- If there is continuity, the circuit is shorted. Repair or replace the harness.
- VDI solenoid valve terminal B (harness-side) and body GND
- VDI solenoid valve terminal A (harness-side) and power supply
