• Check Engine Light is on
• Possible battery performance issues
• Reduced fuel efficiency
• Faulty battery temperature sensor
• Wiring issues, such as short circuits
• Defective Battery Energy Control Module
Battery Energy Control Module: A component that manages and monitors the battery system in a vehicle.
Temperature Sensor: A device that measures temperature and sends this information to the vehicle's computer.
• P1EE6
• P1EE8
This code means that the car's computer has detected a problem with one of the temperature sensors in the battery system. It's like when a thermometer is reading too high, even though it might not be that hot.
The P1EE7 code is triggered when the Battery Energy Control Module detects that the temperature sensor 'B' for the battery is reading a voltage that is higher than expected.
The Battery Energy Control Module monitors various sensors to ensure the battery operates within safe temperature limits. If sensor 'B' reports a voltage that is too high, it may indicate a fault in the sensor circuit, such as a short circuit or a failed sensor.
• Use an OBD-II scanner to confirm the code
• Inspect the wiring and connections for the temperature sensor
• Test the temperature sensor for proper operation
• Replace the faulty temperature sensor
• Repair or replace damaged wiring
• Replace the Battery Energy Control Module if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Volt
• Cadillac ELR
• Chevrolet Spark EV
• Regularly inspect battery connections
• Ensure proper maintenance of the battery system
• Avoid extreme temperatures when possible
Sensor Issue
• Have the vehicle inspected by a professional if the check engine light is on
• Avoid driving the vehicle if you notice performance issues
Check with the vehicle manufacturer for warranty coverage on battery components.
This code is commonly seen in hybrid and electric vehicles where battery temperature management is critical.
Moderate – It should be addressed soon to prevent potential battery damage.
Ignoring this code can lead to battery overheating, which may pose safety risks.
• Vehicle at operating temperature
• Battery system active
The temperature sensor is typically located within the battery pack or near it.
Q: Can I drive with the P1EE7 code?
A: It's not recommended to drive for extended periods with this code, as it may lead to battery issues.
Q: How do I reset the P1EE7 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, further diagnosis is needed.
