When this code is triggered, the Engine Control Module (ECM) has detected that the signal from the battery current sensor is out of the expected range, or that there is a performance discrepancy within the circuit.
The P155B00 diagnostic trouble code (DTC) is a for Nissan vehicles. Unlike standardized OBD-II codes (P0xxx) that are the same across all makes, manufacturer-specific codes like P155B00 relate to proprietary systems and functions unique to Nissan, which is why information about them can sometimes be more difficult to find. The P155B00 code is a manufacturer-specific code, which
: The engine cannot optimize the air-fuel mixture properly. Typical Causes
