This summary uses the existing diagnostic information shown in full below.
The car's computer is having trouble reading the temperature of the battery because the sensor is not working properly all the time.
This code indicates that the temperature sensor for the hybrid or electric vehicle battery is sending intermittent or erratic signals to the car's computer.
The P0C8C code is triggered when the Powertrain Control Module (PCM) detects an intermittent or erratic signal from the battery temperature sensor circuit. This sensor monitors the temperature of the hybrid or electric vehicle battery to ensure it operates within safe limits. An erratic signal can indicate a poor connection, wiring issue, or sensor failure.
• Check Engine Light illuminated
• Reduced fuel efficiency
• Possible battery overheating
• Faulty battery temperature sensor
• Poor connection at the sensor or PCM
• Damaged wiring or connectors
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics II
• Verify the code with an OBD-II scanner.
• Inspect the battery temperature sensor and its wiring for damage.
• Check for loose or corroded connectors.
• Replace the faulty battery temperature sensor.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly inspect battery connections.
• Ensure the vehicle's electrical system is maintained.
• Avoid extreme temperatures when possible.
Sensor Issue
• Have the vehicle inspected by a professional.
• Avoid driving long distances until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on hybrid/EV components.
This code has become more common with the increase in hybrid and electric vehicles, highlighting the importance of battery management systems.
Moderate – While the vehicle may still operate, ignoring the issue could lead to battery damage.
Driving with a faulty battery temperature sensor can lead to overheating and potential safety hazards.
• Vehicle at operating temperature
• Battery under normal load conditions
The battery temperature sensor is typically located near or within the battery pack of the hybrid or electric vehicle.
Q: Can I drive my car with this code?
A: It's not recommended to drive for long distances as it could lead to battery overheating.
Q: How do I clear this code?
A: The code can be cleared with an OBD-II scanner after the issue is fixed.
