Dorman 977-790 Fuel Injection Throttle Body

OE FIX Electronic Throttle Body

This Dorman electronic throttle body is built for direct replacement on select Hyundai and Kia applications, including the Hyundai Veracruz, Azera, Entourage, Sonata, Santa Fe and Kia Sedona, Amanti. Part number 977-790 addresses a common failure point in throttle bodies where moisture and oil intrusion can affect the internal electronics.

Designed with Dorman Sensor Shield technology, this throttle body uses a proprietary butterfly shaft seal to help reduce future contamination-related failures. It features an aluminum throttle body construction, gray finish, 75.44 mm bore diameter, 76.12 mm inlet diameter, and an integrated throttle position sensor.

• Electronic throttle body for gas fuel systems
• Integrated throttle position sensor included
• Aluminum throttle body with aluminum/PBT housing
• Flanged inlet design with non-flanged outlet
• 8-terminal male blade electrical connection
• Gray throttle body finish with natural housing color

Detailed Application Overview

Part number 977-790 is an OE FIX-style replacement for vehicles that use an electronic throttle body and need a direct-fit service part. It is listed for 2006-2011 Hyundai Azera, 2006-2010 Hyundai Sonata, 2007-2010 Hyundai Entourage, 2007-2012 Hyundai Veracruz, 2007-2009 Hyundai Santa Fe, 2006-2010 Kia Sedona, and 2007-2009 Kia Amanti. This part cross-references Standard Ignition (e.g., S20231) for the same application.

What It Helps Address

• Throttle response issues caused by contaminated internal electronics
• Idle instability related to throttle body wear or sensor faults
• Electronic throttle control warning lights tied to throttle body failure
• Driveability problems from a sticking or inconsistent throttle plate
• Replacement needs after moisture or oil intrusion damages the original unit

Installation Notes and Tips

Verify connector style, inlet diameter, and throttle body type before installation. This unit does not include mounting hardware, gasket or seal, or installation hardware, so reuse or source the required service parts as needed. Confirm the vehicle’s electronic throttle system and match the application to the listed Hyundai and Kia fitment before replacement.

Quality Assurance

Dorman OE FIX components are engineered to replace the original part while addressing a known failure mode in the factory design. Sensor Shield technology and the shaft seal are used to help reduce repeat contamination-related throttle body problems.
