The P0A89 fault code refers to a problem with the 14 Volt Power Module Current Sensor in the Engine Control Module (ECM).

This sensor is responsible for monitoring the current in the power module. When the sensor detects that the current is not within the factory specifications, the ECM sets the P0A89 code.

In simpler terms, this fault code indicates that there is a high circuit in the 14 Volt Power Module Current Sensor. This means that the sensor is detecting a higher current than it should be, which can lead to various issues with the vehicle’s electrical system.

It is important to address this issue promptly to prevent further damage and ensure the proper functioning of the vehicle.
