If you’re experiencing engine light issues and have come across the codes P2120, P2121, P2122, or P2123 on your Hyundai Sonata, you’re in the right place. In this article, we’ll walk you through the possible fixes for these codes and introduce you to a reliable diagnostic tool for your vehicle.
First, it’s essential to check the throttle accelerator pedal, as it is a common reason for these codes to appear. Ensure the wiring harness is securely connected and free from any damage. A malfunctioning pedal can often trigger these codes, and we have a dedicated video on our channel that explains how to test the accelerator pedal on a Hyundai.

A broken wire or a dirty throttle body can cause issues with the signal transfer to the engine computer, leading to the appearance of the mentioned codes. We also have videos on our channel demonstrating how to clean or replace the throttle body and accelerator pedal.
Now, let’s talk about the diagnostic tool we use. It’s a versatile computer that supports various vehicles, including the Hyundai Sonata. This tool enables you to read codes from every system in your vehicle and access the computer to see live data. It’s constantly updated, making it an excellent investment for at-home car enthusiasts.
