The P0C71 fault code refers to a correlation issue between hybrid battery temperature sensors ‘D’ and ‘E’.

These sensors are located in three different areas of the HV (high-voltage) battery in the vehicle. Each sensor contains a thermistor that measures the resistance, which changes with the HV battery temperature. 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.

Based on this data, the power management control ECU regulates the blower fan. The blower fan is activated when the HV battery temperature exceeds a predetermined level. The P0C71 fault code indicates that there is a discrepancy or inconsistency between the readings of temperature sensors ‘D’ and ‘E’. This can lead to improper control of the blower fan, potentially affecting the cooling system of the HV battery.

It is important to address this issue promptly to ensure the proper functioning and longevity of the hybrid battery system.

What are the possible causes of the automobile fault code p0c71?

If you see the engine light or service engine soon warning light on, the fault code P0C71 could be the culprit. This code is often caused by a faulty hybrid battery thermistor, a faulty battery smart unit, an open or shorted hybrid battery thermistor harness, or a poor electrical connection in the hybrid battery thermistor circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
