This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer found a problem with the temperature sensors that check how hot or cold the hybrid or electric car's battery is. The sensors are not agreeing with each other.
The vehicle's control module has detected a discrepancy between the readings of two temperature sensors (A and B) in the hybrid or electric vehicle's battery system.
The P0C6E code is triggered when the Powertrain Control Module (PCM) or Battery Energy Control Module (BECM) detects that the readings from battery temperature sensors A and B do not correlate or match within a specified range. These sensors are critical for monitoring the battery's thermal condition to ensure optimal performance and safety.
• Check Engine Light illuminated
• Reduced fuel efficiency
• Possible battery overheating
• Faulty battery temperature sensor
• Wiring issues or poor connection
• Faulty Battery Energy Control Module (BECM)
PCM: Powertrain Control Module
BECM: Battery Energy Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the battery temperature sensors and wiring for damage.
• Check for any loose or corroded connections.
• Replace faulty battery temperature sensor.
• Repair or replace damaged wiring.
• Replace the Battery Energy Control Module if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly inspect battery connections.
• Ensure proper battery maintenance.
• Keep the battery cooling system clean and operational.
Sensor Issue
• Avoid driving aggressively to prevent overheating.
• Schedule regular maintenance checks for the battery system.
Check with your vehicle manufacturer as battery components may be covered under warranty.
This code has become more common as hybrid and electric vehicles have become more prevalent, highlighting the importance of battery management systems.
Moderate – Address the issue to prevent potential battery damage or reduced performance.
Ignoring this code may lead to battery damage or reduced vehicle performance, which could pose safety risks.
• Vehicle at operating temperature
• Battery system under load
Battery temperature sensors are typically located within the battery pack, often near or attached to the battery cells.
Q: Can I drive with the P0C6E code?
A: It's possible, but not recommended. The battery may not be operating efficiently, and there could be a risk of overheating.
Q: How do I reset the P0C6E code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, further diagnosis is needed.
