P0Ac5 Fault Code: Understanding The Description And Implications
The P0AC5 fault code refers to a problem with the Hybrid Battery Temperature Sensor ‘B’ Circuit.
This code indicates an issue with the resistance of the thermistor in the battery temperature sensor. The resistance of the thermistor changes with the temperature of the HV (High Voltage) battery. When the battery temperature is low, the thermistor resistance is high, and when the temperature is high, the resistance is low.
The battery smart unit uses the battery temperature sensors to detect the HV battery temperature and sends this information to the power management control ECU.
The power management control ECU then uses this data to control the blower fan. The blower fan is activated when the HV battery temperature exceeds a predetermined level. If you encounter the P0AC5 fault code, it means there is an issue with the Hybrid Battery Temperature Sensor ‘B’ Circuit.
It is important to address this problem promptly to ensure proper functioning of the battery temperature monitoring system and the blower fan control.
