Detailed Description

This Dorman throttle body, part number 977-830, is engineered as a replacement for electronic throttle control systems on 2007-2013 Mazda 3 and 2007-2012 Mazda CX-7 applications. It uses an aluminum housing, includes the throttle position sensor, and is built to OE-style dimensions and connection points for the listed vehicles. This part cross-references Standard Ignition (e.g., S20167) for the same application.

For buyers searching for a Mazda 3 throttle body replacement or a Mazda CX-7 electronic throttle body, 977-830 provides a direct-fit service part for vehicles experiencing throttle-related fault codes or idle quality concerns. The design focuses on restoring proper airflow control through the electronic throttle system.

What It Is Used For

  • Erratic or unstable idle on Mazda 3 and Mazda CX-7 models
  • Malfunction indicator lamp illumination related to throttle control
  • Throttle body contamination from oil, dirt, or carbon buildup
  • DTCs tied to electronic throttle operation
  • Replacement of a worn or failing OE throttle body

Installation Notes and Tips

Verify connector style, inlet and outlet dimensions, and vehicle application before installation. The gasket is included, while mounting hardware and installation hardware are not included. Because this is an electronic throttle body, follow the vehicle service procedure for throttle relearn or idle relearn steps after installation if required by the application.

Quality Assurance

Dorman builds this replacement throttle body from high-quality materials and to exacting standards to help reduce repeat failures on the specified Mazda applications. It is intended to match original equipment performance on the listed vehicles, including Mazda 3 and Mazda CX-7 models.
