The P0C34 fault code refers to an issue with the HybridEV Battery Temperature Sensor. These sensors are responsible for monitoring the temperature of the battery.

They are located within the battery sections and there are two sensors in each section.

The temperature sensor is a variable resistor that measures the temperature of the battery cell group. It works by changing its resistance based on the battery temperature. When the temperature decreases, the sensor resistance increases, and when the temperature increases, the sensor resistance decreases.

The HybridEV interface control module supplies 5V to the signal circuit and acts as a ground for the low reference circuit.

The temperature sensor values are communicated to the HybridEV Powertrain Control Module via serial data. The Powertrain Control Module uses these values to determine the battery module temperature and control the battery cooling system operation.

The P0C34 fault code is triggered when the difference between a single battery temperature sensor and the average of the other sensors is greater than 25°C (45°F).

This indicates a problem with the performance of the HybridEV Battery Temperature Sensor 6.

What are the possible causes for the automobile fault code p0c34?

If you see the engine light on or the service engine soon warning light, the fault code P0C34 could be the culprit. This code is often caused by a faulty hybrid/EV battery assembly, an open or shorted harness, a poor electrical connection in the hybrid/EV battery assembly circuit, or a faulty hybrid/EV battery interface control module. To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins. Don’t forget to consider the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors to fix the fault code p0c34?
