Detailed Description

This Hitachi fuel injection throttle body is built to maintain accurate engine airflow control and stable throttle response. Precision TPS circuitry helps the engine control system read throttle position correctly, supporting consistent fuel delivery, smooth drivability, and lower emissions output. The ETB0079 is a direct-fit style electronic throttle body for 2011-2019 Toyota Corolla, 2017-2018 Toyota Corolla iM, 2016 Scion iM, and 2011-2014 Toyota Matrix applications. This part cross-references Standard Ignition S20139 for the same application.

Common Issues This Part Can Help Resolve

• Throttle response delay or hesitation
• Rough idle caused by throttle body wear or contamination
• Electronic throttle control faults related to sensor or circuit issues
• Airflow inconsistency affecting fuel economy and drivability
• Check engine light concerns tied to throttle position readings

Installation Notes and Tips

Verify connector style, bore size, and OE part number before installation. Because no gasket or seal is included, inspect the sealing surface and replace any required sealing components separately. After installation, perform any throttle relearn or idle relearn procedure specified by the vehicle manufacturer for Toyota Corolla, Corolla iM, Scion iM, or Matrix service.

Quality Assurance

Hitachi designs its electronic throttle bodies with durable materials, protected circuitry, and application-specific calibration to support accurate engine mapping and reliable operation under demanding conditions.
