When it comes to Honda P0122 Code, it’s a common problem that can cause a variety of issues with your vehicle. The code stands for Throttle Position (TP) Sensor A Circuit Low Voltage, meaning that the voltage being sent from the TP sensor isn’t reaching the expected level. It’s important to understand the causes and solutions to this problem in order to ensure your vehicle’s health. There are a variety of causes for Honda P0122 Code, including poor connections or loose terminals at the throttle body and the PCM, an “open” or “short” circuit between the throttle body and the PCM, a faulty TP sensor A, an outdated PCM software, and a faulty PCM.
Causes and Solutions for Honda P0122 Code
| Cause | Solution |
|---|---|
| Poor connections or loose terminals at the throttle body and the PCM | Check and tighten connections and terminals |
| “Open” or “Short” circuit between the throttle body and the PCM | Check and repair any open or short circuits |
| Faulty TP sensor A, replace throttle body | Replace the throttle body |
| Update the PCM if it does not have the latest software, or substitute a known-good PCM | Update the PCM software or replace with a known-good PCM |
| Faulty PCM | Replace the faulty PCM |
Poor Connections or Loose Terminals at the Throttle Body and the PCM
If the Honda P0122 Code is caused by poor connections or loose terminals at the throttle body and the PCM, the best solution is to check and tighten all the connections and terminals. This will help ensure that the signal from the TP sensor is reaching the PCM at the expected level.
Open or Short Circuit Between the Throttle Body and the PCM
The code can also be caused by an open or short circuit between the throttle body and the PCM. If this is the case, it is important to check and repair any open or short circuits between the two components. This will ensure the signal from the TP sensor is reaching the PCM with the expected level.
Faulty TP Sensor A or Faulty PCM
If the Honda P0122 Code is caused by a faulty TP sensor A or a faulty PCM, the best solution is to replace the faulty component. If the TP sensor A is faulty, it is important to replace the throttle body, as this will help ensure the signal from the TP sensor is reaching the PCM with the expected level. If the PCM is faulty, it is important to replace the faulty PCM with a new one.
Outdated PCM Software
If the Honda P0122 Code is caused by an outdated PCM software, the best solution is to update the PCM software. This will help ensure the signal from the TP sensor is reaching the PCM with the expected level. Alternatively, if the PCM is outdated, it is important to substitute it with a known-good PCM.
Conclusion
In conclusion, Honda P0122 Code can be caused by a variety of issues with the vehicle, including poor connections or loose terminals at the throttle body and the PCM, an “open” or “short” circuit between the throttle body and the PCM, a faulty TP sensor A, an outdated PCM software, and a faulty PCM. It is important to diagnose the issue and take the necessary steps to repair or replace the faulty components to ensure the health of the vehicle. By following the above-mentioned solutions for the Honda P0122 Code, you can ensure your vehicle is running smoothly.
