Variable Induction Control Solenoid: Testing and Inspection
VARIABLE INTAKE-AIR SOLENOID VALVE INSPECTION1. 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 2AJ
- Variable intake-air solenoid valve terminal B and main relay terminal A
Short circuit
- If there is continuity, the circuit is shorted. Repair or replace the wiring harness.
- Variable intake-air solenoid valve terminal B and body GND
- Variable intake-air solenoid valve terminal A and power supply
