What is OBD-II Code P2D84 – Battery Charger B Input Current Sensor Circuit High
When it comes to keeping your car in tip-top shape, one of the most important things you can do is keep an eye on your car’s diagnostic trouble codes (DTCs). These codes are signals from your car’s onboard computer that indicate something is wrong with your vehicle. One of these codes is OBD-II Code P2D84 – Battery Charger B Input Current Sensor Circuit High. In this article, we’ll explain what this code means, what causes it, and how you can go about repairing the issue.
What is OBD-II Code P2D84?
OBD-II Code P2D84 refers to the battery charger B input current sensor and the circuit that it is a part of. The battery charger B input current sensor is responsible for reading the amount of current that is being put into the battery while it is charging. If the sensor detects that the current is too high, the OBD-II system will trigger a fault code.
What Causes Code P2D84?
There are several possible causes of OBD-II Code P2D84. These include:
1. A problem with the battery charger itself. If the charger is malfunctioning in some way, it could be causing the current to be too high.
2. A faulty battery. If the battery is not accepting the charge correctly, it could cause the current to be too high.
3. Loose or damaged wiring. If the wiring that connects the charger and battery is loose or damaged, it could be causing the current to be too high.
4. A malfunctioning current sensor. If the current sensor itself is not functioning correctly, it could be causing the code to be triggered.
How to Repair Code P2D84
The steps for repairing OBD-II Code P2D84 will depend on the specific cause of the issue. Here are some general steps you can take to fix this problem:
1. Check the battery and charger. Start by checking the battery and charger themselves to make sure they are functioning properly.
2. Inspect the wiring. Check the wiring that connects the battery and charger to make sure it is not loose or damaged.
3. Test the current sensor. Test the current sensor to make sure it is functioning properly.
4. Replace any faulty components. If you find any faulty components during your inspection, replace them as needed.
5. Clear the fault code. Once you have made the necessary repairs, use an OBD-II scanner to clear the fault code.
