P0C86 Fault Code: Understanding The Description And Troubleshooting Steps
The P0C86 fault code refers to a problem with the Hybrid Battery Temperature Sensor ‘FG’ correlation. This fault code indicates that there is an issue with the correlation between the temperature sensors located in the HV (High Voltage) battery of the hybrid vehicle.
The HV battery has three temperature sensors, and each sensor contains a thermistor that measures the resistance based on the battery temperature.
The resistance of the thermistor changes as the battery temperature fluctuates. When the battery temperature is low, the thermistor resistance is high, and vice versa.
The battery smart unit utilizes these temperature sensors to detect the HV battery temperature and sends the 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.
However, when the P0C86 fault code is triggered, it means that there is a discrepancy or inconsistency between the readings of the ‘F’ and ‘G’ temperature sensors.
This can lead to improper control of the blower fan, potentially causing issues with the HV battery’s temperature regulation.
It is important to address this fault code promptly to ensure the proper functioning and longevity of the hybrid vehicle’s battery system.
FAQ
