The P0AB2 fault code refers to the Hybrid Battery Pack Air Temperature Sensor ‘B’ Circuit RangePerformance.

This sensor is located on the HV battery assembly and measures the intake air temperature.

Its resistance value changes with variations in the intake air temperature, similar to the battery temperature sensors.

The battery ECU utilizes the signals from the intake air temperature sensor to regulate the air flow speed of the battery blower assembly.

When the P0AB2 code is triggered, it indicates that there is an issue with the circuit range or performance of the Hybrid Battery Pack Air Temperature Sensor ‘B’. This fault code should be addressed promptly to ensure proper functioning of the hybrid battery system.
