Hitachi ETB0091 Electronic Throttle Body

Hitachi ETB0091 is an electric fuel injection throttle body built for precise throttle control, fast response, and stable engine mapping. It is a direct-fit style replacement for select Toyota and Lexus hybrid applications, including Corolla, Prius, Prius Prime, Prius V, and CT200h models.

• Electric throttle body with integrated throttle position sensor
• 55.0 mm bore diameter for the specified application
• Rectangle connector shape with 6 male blade terminals
• New unit from Hitachi
• No gasket or seal included
• No idle air control motor included

Precision Throttle Control

This Hitachi fuel injection throttle body uses electric actuation and TPS circuitry to help maintain accurate throttle response and engine mapping. The design focuses on consistent airflow control, which supports smooth drivability, fuel economy, and lower emissions in the vehicles it was engineered for. ETB0091 is built with durable internal components and protected circuitry for long-term reliability in demanding operating conditions.

Compatible With 2022-2025 Toyota Corolla, 2010-2022 Toyota Prius, 2022 Toyota Prius AWD-e, 2018-2022 Toyota Prius Prime, 2013-2018 Toyota Prius V, and 2012-2017 Lexus CT200h. It also fits select Prius Plug-In and Prius AWD-e applications by model year and configuration. This part cross-references Frenkit (e.g., S20133) for the same application.

Common Replacement Reasons

• Throttle response delay or inconsistent acceleration
• Rough idle caused by throttle plate control issues
• Electronic throttle fault codes related to the throttle body or TPS circuit
• Reduced fuel economy from inaccurate air metering
• Emissions concerns tied to unstable engine mapping

Installation Notes

Verify connector style, terminal count, and bore size before installation. ETB0091 uses a rectangular 6-terminal blade connector and includes the throttle position sensor, but does not include a gasket or seal. Clean the intake mating surface and confirm the throttle body matches the original unit for the specific Toyota Prius, Toyota Corolla, or Lexus CT200h application before final assembly.

Quality Assurance

Hitachi designs this electronic throttle body to meet the exact requirements of the listed vehicle applications, with attention to material durability, protected circuitry, and accurate sensor feedback. The result is a replacement throttle body engineered for dependable operation in the intended Toyota and Lexus hybrid platforms.
