Electronic Throttle Body for Toyota Aqua / Prius

Description

This is a used, genuine OEM electronic throttle body assembly for the Toyota Aqua, also known as the Prius C, equipped with the 1NZ-FXE 1.5L hybrid engine. This is not just a throttle body; it is an integrated unit that includes the main throttle body, the electronic throttle control motor, and the Exhaust Gas Recirculation (EGR) valve assembly.[1][2]

This complex component is critical for the proper functioning of Toyota’s hybrid synergy drive system. The throttle body regulates air intake, while the EGR valve recirculates a portion of the exhaust gas back into the engine cylinders.[2] This process lowers combustion temperatures, which improves fuel efficiency and reduces harmful NOx emissions, a key feature of the Atkinson-cycle engine used in these hybrids.[2]

A faulty throttle body or a clogged EGR system can lead to a variety of issues, including a rough idle, poor engine performance, decreased fuel economy, and the illumination of the check engine light with related trouble codes. This assembly is a direct replacement for part number 22030-21030 and is also compatible with other Toyota models using the 1NZ-FE engine, such as the Yaris, although the integrated EGR valve is specific to hybrid applications.[3][4][5]

Important Note: The electrical pigtail connector on this unit has been cut and will require professional repair by splicing it into your vehicle’s existing wiring harness. Please examine all photos carefully before purchasing.
