When a Hyundai is experiencing a P0722 code, the issue is with the output shaft speed sensor. This code is triggered when the vehicle is in drive, second, or first gear and the input shaft speed is over 775 RPM, and the PCM does not detect any OSS sensor signal. This can be a difficult issue for drivers to troubleshoot as they have to identify the underlying cause of the code. This article will provide a comprehensive overview of the causes and solutions for the Hyundai P0722 code.
Causes and Solutions for Hyundai P0722 Code
| Causes | Solutions |
|---|---|
| Output Shaft Speed Sensor Signal Circuit Open or Shorted | Check circuit for continuity or short |
| Output Shaft Speed Sensor is Damaged or Failed | Replace or Repair Sensor |
| PCM has Failed | Replace PCM |
| Incorrect Software | Reprogram PCM |
Output Shaft Speed Sensor Signal Circuit Open or Shorted
When the output shaft speed sensor signal circuit is open or shorted, the Hyundai P0722 code will be triggered. The cause of this issue can be anything from a broken wire in the harness to a faulty connection. To identify the issue, the driver must first check the circuit for continuity or short.
Output Shaft Speed Sensor is Damaged or Failed
When the output shaft speed sensor is damaged or failed, it will cause the Hyundai P0722 code to be triggered. In this case, the best solution is to replace or repair the sensor. However, if the sensor is beyond repair, then it must be replaced with a new one.
PCM has Failed
If the Powertrain Control Module (PCM) has failed, then it can trigger the Hyundai P0722 code. In this case, the best solution is to replace the PCM. However, it is important to note that the PCM must be programmed with the correct software.
Incorrect Software
If the PCM has been programmed with incorrect software, it can cause the Hyundai P0722 code to be triggered. In this case, the best solution is to reprogram the PCM with the correct software.
Conclusion
The Hyundai P0722 code is triggered when the vehicle is in drive, second, or first gear and the input shaft speed is over 775 RPM, and the PCM does not detect any OSS sensor signal. This code is caused by a variety of factors, including a broken wire in the harness, a faulty connection, a damaged or failed output shaft speed sensor, a failed PCM, and incorrect software. To identify the underlying cause of the code, it is important to check the circuit for continuity or short, replace or repair the sensor, replace the PCM, and reprogram the PCM with the correct software. By following these solutions, drivers can effectively troubleshoot and resolve the Hyundai P0722 code.
