This code means that the car's computer has detected a problem with one of the sensors that checks how hot or cold the hybrid or electric car's battery is. It's like when a thermometer isn't working right and can't tell the temperature correctly.
The P0C94 code indicates that the voltage from the Hybrid/EV Battery Temperature Sensor K is lower than the expected range, suggesting a potential issue with the sensor or its circuit.
The Hybrid/EV Battery Temperature Sensor K monitors the temperature of the battery pack to ensure it operates within safe limits. A low circuit signal suggests that the sensor is reporting a temperature reading that is too low, possibly due to a wiring issue, sensor malfunction, or connectivity problem.
• Check engine light on
• Reduced battery performance
• Possible battery overheating
• Faulty battery temperature sensor
• Damaged wiring or connectors
• Faulty battery management system

Battery-related issues may be covered under the vehicle's hybrid or EV warranty.
This code has been reported in various hybrid and electric vehicles, often related to sensor or wiring issues.
Moderate – It's important to address this issue to prevent potential battery damage.
Ignoring this code could lead to battery overheating, which may pose safety risks.
• Vehicle in park with the ignition on.
• Battery at normal operating temperature.
The battery temperature sensor is typically located within the battery pack or near the battery management system.
Q: Can I drive my car with this code?
A: It's best to have it checked soon, as driving with this issue could lead to battery problems.
Q: How do I reset the check engine light?
A: After repairs, use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes.
