P0C34 Possible Causes
- Hybrid battery thermistor
- Battery smart unit
- Wire harness or connector
First diagnose P0C34 code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
Cost of diagnosing the P0C34 code
Labor: 1.0The cost of diagnosing the P0C34 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
P0C34 Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P0C34 MeaningThe battery temperature sensors are provided at 3 locations of the HV battery. The resistance of the thermistor, which is built into each battery temperature sensor, varies in accordance with changes in the HV battery temperature. The lower the battery temperature, the higher the thermistor resistance. Conversely, the higher the temperature, the lower the resistance. The battery smart unit uses the battery temperature sensors to detect the 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 blower fan. (The blower fan starts when HV battery temperature rises above a predetermined level.)
