When a vehicle idles roughly, displays a malfunction indicator lamp or sets DTCs, the cause might be oil ingress or dirt and carbon buildup in the electronic throttle body. This 100% new electronic throttle body is designed to match the fit and function of the original equipment throttle body on specified vehicles. It features a non-contact Hall effect sensor and proprietary Sensor Shield butterfly shaft seal to help prevent future failures. This part is compatible with the following vehicles. Before purchasing, enter your vehicle trim in the garage tool to confirm fitment. [Toyota Corolla: 2020, 2021]
