Code P1EBA Description

The P1EBA code indicates that the Hybrid/EV battery low-resolution current sensor has exceeded its learning limit. In hybrid and electric vehicles, the current sensor is a crucial component that measures the flow of electrical current in the battery system. When the sensor detects that the current has exceeded the learning limit, it means that the sensor is unable to accurately measure the current, which can lead to various issues within the vehicle's electrical system.
