Troubleshooting Hyundai Sonata P2106 Error Code

When your Hyundai Sonata's dashboard lights up with a P2106 error code, it indicates a serious issue concerning the throttle actuator control system. This code suggests that your vehicle's Electronic Control Module (ECM) has forcibly limited the power output of the engine due to a detected malfunction. Understanding and addressing this error promptly can prevent further damage to your vehicle. Here’s a detailed guide on how to diagnose and resolve the P2106 error code in your Hyundai Sonata.

What is the P2106 Error Code?

Step 2: Visual Inspection

Conduct a thorough visual inspection of the throttle body, wiring, and connectors. Look for any signs of damage, disconnections, or corrosion that might affect the system's performance.

Test the throttle actuator and the throttle body to ensure they are functioning correctly. Replace them if they show signs of malfunction or wear.

Step 4: Test the Accelerator Pedal Position Sensor

Evaluate the performance of the accelerator pedal position sensor. A faulty sensor can send incorrect signals to the ECM, leading to the P2106 code.
