Key Features

• Hitachi ABV0031 idle air control valve for fuel injection system service
• 16mm port inside diameter for the specified OE application
• 2-terminal male blade connector layout with 1 connector interface
• Direct replacement reference for E9DZ-9F715-AA
• OE-grade fitment for select Ford and Mercury models

Detailed Description

Built for air and fuel delivery systems, the Hitachi ABV0031 helps regulate bypass air around the throttle body so the engine can maintain a controlled idle speed. This part number is listed for 1989-1994 Ford Aerostar, 1991-1992 Ford Ranger, 1991 Ford Escort, 1991 Mercury Tracer, and 1989-1990 Mercury Sable applications. If you are replacing a worn idle air control valve on a Ford Aerostar or Ford Ranger, ABV0031 provides the OE-style configuration needed for proper electrical and port match-up. The part cross-references E9DZ-9F715-AA for the same application.

Common Issues This Part Can Address

• Unstable or fluctuating idle speed
• Engine stalling when coming to a stop
• Idle speed that is too high or too low
• Rough idle after throttle release
• Idle control problems caused by a failing valve or restricted airflow passage

Installation Notes and Tips

Verify the connector style, terminal count, and port diameter before installation. This valve uses a 16mm port inside diameter and a male blade terminal design, so matching the OE connector and intake opening is important for proper fitment. Clean the throttle body and surrounding air passages during service to help restore consistent idle control. Confirm vehicle application by year, make, and model before ordering.

Quality Assurance

Hitachi manufactures this idle air control valve as an OE-grade replacement component for the listed Ford and Mercury applications. The ABV0031 is built to match the specified factory-style configuration for direct service use.
