Air Switching Valve Removal/Installation
Air Switching Valve Inspection
If the air switching valve [A] is normal, check the wiring for continuity (see Air Switching Valve Circuit).
Special Tool - Hand Tester: 57001-1394
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).
