Laymans terms

This code means that the car's computer has detected a problem with the sensor that measures how much electricity is coming into the car's battery charger. It's like when a toy's battery charger is plugged in but the light is blinking because something's wrong.

Explanation

The P0D3B code indicates that the input current sensor for the battery charger is reading a higher than expected value.

Technical description

The Battery Charger A Input Current Sensor monitors the amount of current entering the battery charger. If the sensor detects a current level that is higher than the expected range, the vehicle's control module will trigger the P0D3B code. This could be due to a malfunctioning sensor, wiring issues, or a problem with the battery charger itself.
