When it comes to Honda vehicles, one of the most common and serious issues is the P0098 code. This code, which stands for “Intake Air Temperature (IAT) Sensor 2 Circuit High Voltage,” is caused by a few different factors and can be difficult to diagnose and repair. From poor connections or loose terminals at the IAT sensor and the PCM, to an “open” circuit between the PCM and IAT sensor to a faulty sensor or PCM, all can lead to this code being triggered. In some cases, the PCM even needs to be updated with the latest software. It’s important to understand the causes and solutions to this code in order to make sure that your Honda vehicle is running as smoothly as possible.
Causes and Solutions of Honda P0098 Code
| Cause | Solution |
|---|---|
| Poor connections or loose terminals at IAT sensor 2 and the PCM | Thoroughly inspect the connections to ensure they are secure and no corrosion is present |
| “Open” circuit between the PCM and IAT sensor 2 | Check the wiring for any damage and repair if necessary |
| Faulty IAT sensor 2 | Replace the IAT sensor 2 with a new one |
| PCM needs to be updated with the latest software | Take the vehicle to the dealership to have the software updated |
| Faulty PCM | Replace the PCM with a new one |
Poor Connections or Loose Terminals
When the P0098 code is triggered in a Honda vehicle, one of the most common causes is poor connections or loose terminals at the IAT sensor and the PCM. If the connections are not properly secured, it can cause the P0098 code to be triggered. In order to remedy this issue, it is important to inspect the connections and ensure they are secure. Additionally, it is important to look for any signs of corrosion on the terminals, as this can also lead to the code being triggered.
Open Circuit Between PCM and IAT Sensor
Another cause of the P0098 code in Honda vehicles is an “open” circuit between the PCM and IAT sensor. This means that there is a break in the connection, which can be caused by wiring damage. If this issue is present, a thorough inspection of the wiring should be conducted to locate and repair any damage.
Faulty IAT Sensor and PCM
In some cases, the P0098 code can be triggered by a faulty IAT sensor or PCM. If this is the case, then the faulty component must be replaced with a new one. If the IAT sensor is the problem, then it should be replaced with a new one. If it is the PCM that is at fault, then it should be replaced as well.
PCM Needs to be Updated with the Latest Software
The P0098 code can also be triggered if the PCM needs to be updated with the latest software. In this case, the vehicle must be taken to the dealership in order to have the software updated. This is an important step in remedying the issue, as it ensures that the PCM is up to date and working properly.
Conclusion
The Honda P0098 code is a serious issue that can be caused by a few different factors. From poor connections or loose terminals at the IAT sensor and the PCM, to an “open” circuit between the PCM and IAT sensor to a faulty sensor or PCM, all can lead to this code being triggered. It is important to understand the causes and solutions to this code in order to make sure that your Honda vehicle is running as smoothly as possible. By taking the necessary steps to diagnose and repair the Honda P0098 code, you can ensure that your vehicle is running optimally.
