P0AB5 Meaning
The intake air temperature sensor is provided on the HV battery assembly. Its resistance value varies with changes in intake air temperature. The characteristics of the intake air temperature sensor are the same as those of the battery temperature sensors.
The battery computer uses signals from the intake air temperature sensor to adjust the airflow speed of the battery fan assembly.
