Having a Hyundai car that has been diagnosed with Code P2173 can be a stressful and worrisome experience. This code is an indication of an Electronic Throttle Control (ETC) System Malfunction- High Air Flow Detected. This error code indicates that the engine airflow measurements are not based on throttle position and are compared with throttle position based on estimated airflow. If the measured airflow is much higher, the throttle body may not be throttling the engine properly.

Causes and Solutions of Hyundai Code P2173
| Causes | Solutions |
|---|---|
| Air leakage between TPS and MAFS | Replace the throttle body and check for any air leakage |
| Faulty throttle body | Replace the throttle body |
| Faulty PCM | Replace the PCM |
| Faulty MAF Sensor | Replace the MAF Sensor |
When driving a Hyundai with the Code P2173, the engine will be running, and the throttle actuation mode is not off. In addition, the MAP sensor and the IAT sensor may not have failed. In order to identify the cause of the problem, it is essential to check for any air leakage between the TPS and MAFS and to check the throttle body and the PCM for faults. Depending on the cause of the error code, the solutions may include replacing the throttle body, checking for air leakage, and replacing the PCM.
Air Leakage Between TPS and MAFS
Air leakage between the throttle position sensor (TPS) and the Mass Air Flow Sensor (MAF) can cause the Hyundai Code P2173. The TPS and the MAFS are responsible for monitoring the amount of air entering the engine and the throttle position. If there is an air leakage, the engine cannot accurately measure the amount of air entering the engine and the throttle position. The solution to this problem is to replace the throttle body and check for any air leakage.
Faulty Throttle Body
A faulty throttle body can also cause the Hyundai Code P2173. The throttle body is responsible for controlling the amount of air entering the engine. If the throttle body is faulty, it will not be able to accurately control the amount of air entering the engine, causing the engine to run improperly. The solution to this problem is to replace the throttle body.
Faulty PCM
The powertrain control module (PCM) is responsible for controlling the engine and the vehicle’s systems. If the PCM is faulty, it cannot accurately control the engine and the vehicle’s systems, leading to the P2173 code. The solution to this problem is to replace the PCM.
Faulty MAF Sensor
The MAF sensor is responsible for monitoring the amount of air entering the engine. If the MAF sensor is faulty, it cannot accurately measure the amount of air entering the engine, causing the engine to run improperly. The solution to this problem is to replace the MAF sensor.
Conclusion
Having a Hyundai vehicle diagnosed with Code P2173 can be a challenging experience. The cause of this code can be caused by air leakage between the TPS and MAFS, a faulty throttle body, a faulty PCM, or a faulty MAF sensor. In order to resolve the Hyundai code P2173, it is essential to identify the cause of the problem and find the appropriate solution. Replacing the throttle body, checking for air leakage, and replacing the PCM or MAF sensor are the most common solutions to the Hyundai Code P2173.
