Have you ever experienced a Honda P0202 Code? If yes, then you are probably familiar with the hassle it can cause. Honda P0202 Code is a No. 2 Cylinder Injector Circuit Malfunction. It is triggered when the return signal from the injector does not change at least 30 times (counts once per engine cycle). Although this issue is easily identifiable, it still needs to be addressed and fixed promptly. In this article, we will go into more detail about the possible causes and solutions of the Honda P0202 Code.
Causes and Solutions of Honda P0202 Code
| Causes | Solutions |
|---|---|
| No. 2 injector INJ_1 line open | Check the wiring harness and repair if necessary |
| No. 2 injector INJ_1 line short to ground | Replace the injector and the wiring harness |
| No. 2 injector INJ_1 line short to power | Install a new injector and check for any shorts |
| No. 2 injector power supply line open | Replace the wiring harness and the injector |
No. 2 Injector INJ_1 Line Open
One of the possible causes of Honda P0202 Code is a broken or open No. 2 injector INJ_1 line. In this case, the signal between the ECM and the injectors is interrupted and the return signal does not change. The first step to fix this issue is to check the wiring harness and repair any connections if necessary.
No. 2 Injector INJ_1 Line Short to Ground
Another possible cause of the Honda P0202 Code is a short to ground in the No. 2 injector INJ_1 line. This short can cause the signal between the ECM and the injectors to be disrupted, leading to a No. 2 Cylinder Injector Circuit Malfunction. To fix this issue, the faulty injector and wiring harness must be replaced.
No. 2 Injector INJ_1 Line Short to Power
The Honda P0202 Code can also be triggered by a short to power in the No. 2 injector INJ_1 line. In this case, an excessive amount of current will be sent to the injectors, resulting in a No. 2 Cylinder Injector Circuit Malfunction. To fix this issue, a new injector must be installed and any shorts must be checked.
No. 2 Injector Power Supply Line Open
The last possible cause of the Honda P0202 Code is an open No. 2 injector power supply line. This can cause the return signal from the injector to not change at least 30 times (counts once per engine cycle). To fix this issue, the wiring harness and injector must be replaced.
Conclusion
Honda P0202 Code is a No. 2 Cylinder Injector Circuit Malfunction. It can be caused by a variety of issues, such as an open No. 2 injector INJ_1 line, a short to ground in the No. 2 injector INJ_1 line, a short to power in the No. 2 injector INJ_1 line, or an open No. 2 injector power supply line. To fix these issues, the wiring harness and injector must be checked and repaired if necessary. In order to avoid the hassle of dealing with the Honda P0202 Code, it is important to regularly inspect and maintain your vehicle.
