How to Fix Code P0C32

Check the “Possible Causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

P0C32 Possible Symptoms

Check engine light illuminated (or service engine soon warning light)

P0C32 Meaning

The battery temperature sensors are provided at 3 locations of the HV battery. The thermistor resistance, built into each battery temperature sensor, varies according to changes in HV battery temperature. The lower the battery temperature, the higher the thermistor resistance. Conversely, the higher the temperature, the lower the resistance. The smart battery unit uses the battery temperature sensors to detect HV battery temperature and sends the detected value to the power management control ECU. Based on the results of this detection, the power management control ECU controls the fan motor. (The fan motor starts when the HV battery temperature exceeds a predetermined level.)
