Driving your Hyundai is usually a smooth experience, but sometimes you may get a more difficult code to diagnose. If you have a Hyundai code P0223, then you may be experiencing a Throttle/Pedal Position Sensor/Switch “B” Circuit High Input. This code means that the output voltage of the TPS 1 is higher than the threshold value, and the TPS 2 is normal. This is an issue that requires a professional to diagnose and repair. Common causes of the P0223 code include poor connection, open or short to ground in the TPS circuit, faulty TPS, and potentially a faulty PCM. To diagnose and repair the issue, a professional must inspect the connectors for poor connection, check the TPS circuit for open or short to ground, and replace the TPS and potentially the PCM.

Causes and Solutions for Hyundai Code P0223
| Cause | Solution |
|---|---|
| Poor connection | Check the connectors for poor connection |
| Open or short to ground in TPS circuit | Check for loose or fast to-ground in the TPS circuit |
| Faulty TPS | Replace the TPS |
| Faulty PCM | Replace the PCM |
Poor Connection
A poor connection is often the root cause of Hyundai code P0223. When the connection is poor, the voltage output of the TPS 1 is higher than the threshold value. To fix this issue, a professional needs to inspect the connectors and ensure they are properly connected.
Open or Short to Ground in the TPS Circuit
Another common issue that can cause Hyundai code P0223 is open or short to ground in the TPS circuit. If the TPS circuit is open or short to bed, it can cause the voltage output of the TPS 1 to be higher than the threshold value. To fix this issue, a professional needs to check for any signs of an open or short-to-ground in the TPS circuit.

Faulty TPS
If the TPS is faulty, it can also cause Hyundai code P0223. If the TPS is incorrect, the voltage output of the TPS 1 will be higher than the threshold value, and the TPS 2 will be normal. To fix this issue, a professional needs to replace the TPS.
Faulty PCM
In some cases, a faulty PCM can cause Hyundai code P0223. If the PCM is defective, it can cause the voltage output of the TPS 1 to be higher than the threshold value. To fix this issue, a professional needs to replace the PCM.
Conclusion: Repairing Hyundai Code P0223
Hyundai code P0223 is an issue that can be difficult to diagnose and repair. If you are experiencing code P0223, then it is important to have it checked by a professional. Common causes of the P0223 code include poor connection, open or short to ground in the TPS circuit, faulty TPS, and potentially a faulty PCM. To diagnose and repair the issue, a professional must inspect the connectors for poor connection, check the TPS circuit for open or short to ground, and replace the TPS and potentially the PCM.
