WAI ETBW122 Electronic Throttle Body Assembly

The WAI ETBW122 is a direct-fit replacement electronic throttle body (ETB) engineered to restore precise airflow control and throttle response to your vehicle. WAI Global is a trusted OEM-level supplier of engine management and electrical components, and this throttle body is designed to meet original equipment form, fit, and function standards.

The electronic throttle body is a core component of the electronic throttle control (ETC) system, also known as drive-by-wire. Rather than relying on a mechanical cable, it uses electronic signals from the accelerator pedal position sensor to command a small internal motor, which opens and closes the butterfly valve to regulate airflow into the engine. This allows the engine control module (ECM) to precisely manage throttle response, idle stability, fuel economy, and emissions.

Key Features:

• Direct OEM replacement — matches original equipment specifications for proper fit and function
• Includes integrated throttle position sensor (TPS) for accurate signal output to the ECM
• Internal DC motor controls butterfly valve position for smooth, responsive throttle actuation
• Helps resolve symptoms such as rough idle, stalling, poor acceleration, and throttle hesitation
• Plug-and-play installation using the existing vehicle wiring harness connector
• Built to WAI Global's OEM-grade quality standards

Common symptoms of a failing electronic throttle body include rough or erratic idle, unexpected stalling, sluggish or uneven acceleration, and illuminated check engine lights related to throttle control circuits. Replacing the throttle body with a quality OEM-equivalent unit like the WAI ETBW122 can restore normal engine performance and drivability.
