Air Intake Solenoid Valve Inspection

Air Intake Solenoid Valve Inspection


If the air intake solenoid valve [A] is normal, check the wiring for continuity (see Air Intake Solenoid Valve Circuit).

If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).

If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).
