The P0C70 fault code refers to a problem with the Hybrid Battery Temperature Sensor ‘CD’ correlation. This code indicates that there is an issue with the temperature sensors located in three different areas of the HV (High Voltage) battery. These sensors have built-in thermistors that measure the resistance, which changes with the battery temperature.

The battery smart unit uses 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 controls the blower fan.

When the HV battery temperature exceeds a predetermined level, the blower fan is activated.

If you encounter the P0C70 fault code, it means that there is a problem with the correlation between the Hybrid Battery Temperature Sensor ‘C’ and ‘D’.

This issue can affect the accuracy of the temperature readings and may result in improper control of the blower fan. It is important to address this fault code promptly to ensure proper functioning of the HV battery and prevent any potential damage.

What are the possible causes of the automobile fault code p0c70?

If you see the engine light or service engine soon warning light on, the fault code P0C70 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, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look out for broken, bent, pushed out, or corroded connector pins.
