Hitachi ETB0129 Electronic Throttle Body Assembly

The Hitachi ETB0129 is a direct-fit electronic throttle body assembly engineered to OEM specifications. Hitachi Auto Products is a trusted OEM supplier to major Asian and domestic automakers, and this throttle body is built to match the original equipment unit it replaces — delivering reliable throttle response, precise airflow control, and long-term durability.

The electronic throttle body works in conjunction with the vehicle's throttle position sensor (TPS) and engine control module (ECM) to regulate the amount of air entering the intake manifold. A properly functioning throttle body is critical for smooth idle, accurate throttle response, and overall engine performance.

Key Features:

• Direct OEM replacement — no modifications required for installation
• Built to original equipment specifications for precise fit and function
• Integrated throttle position sensor for accurate ECM communication
• Manufactured by Hitachi, a recognized OEM supplier to major automakers
• Helps restore proper idle quality, throttle response, and fuel efficiency
• Designed for long service life under normal operating conditions

The Hitachi ETB0129 throttle body is an ideal solution for restoring factory-level performance when the original unit shows signs of failure such as rough idle, hesitation, stalling, or a throttle-related diagnostic trouble code (DTC). As a direct-fit unit, it is designed to drop into place using the original mounting hardware and electrical connectors.
