The fault code P155B00 is associated with a specific problem that the vehicle's onboard computer, or Engine Control Module (ECM), has detected. Unfortunately, without direct access to a current database or a specific manufacturer's code list, providing a precise definition of this code can be challenging. However, I'll provide a general approach to understanding and potentially resolving issues related to OBD-II codes.
Nissan vehicles utilize a "Deceleration Fuel Cut System." To make this system work efficiently, the Engine Control Module (ECM) needs to know exactly how much power the alternator is putting out. It does this via the Battery Current Sensor, which is attached to the negative battery terminal.
Code P155B00 indicates that the signal coming from this sensor is irrational. The ECM expects the sensor data to align with the vehicle's electrical load, but it has detected a "Range/Performance" issue—meaning the data is out of bounds, stuck, or fluctuating incorrectly.
