This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the electrical wire that helps the car's computer talk to the battery sensor. It's like when a walkie-talkie isn't working because the wire is broken.
The P15CE code indicates an issue with the electrical circuit that connects the battery sensor to the vehicle's control module. This circuit is responsible for waking up the sensor to monitor battery conditions.
The P15CE code is triggered when the vehicle's control module detects an electrical fault in the wakeup cable circuit of the battery sensor. This circuit is crucial for ensuring the sensor can communicate battery status effectively to the control module, which helps in managing the battery's health and charging system.
• Check engine light is on
• Battery warning light may illuminate
• Erratic battery charge levels
• Damaged or corroded wiring in the wakeup circuit
• Faulty battery sensor
• Poor electrical connections
Battery Sensor: A device that monitors the battery's condition and communicates with the vehicle's control module.
Wakeup Circuit: An electrical circuit that activates the sensor to start monitoring.
• Inspect the wiring and connections in the wakeup circuit for damage or corrosion.
• Test the battery sensor for proper operation.
• Check the vehicle's control module for any additional fault codes.
• Repair or replace damaged wiring in the wakeup circuit.
• Replace the faulty battery sensor if needed.
• Ensure all electrical connections are clean and secure.
• Multimeter
• OBD-II scanner
• Wire repair kit

Moderate
• Chevrolet Malibu
• Buick Regal
• GMC Acadia
• Regularly inspect battery and sensor connections.
• Keep battery terminals clean and free from corrosion.
• Schedule routine vehicle maintenance.
Sensor Issue
• Do not ignore the check engine light.
• Have the vehicle inspected by a professional if unsure.
Check with the vehicle manufacturer for specific warranty coverage related to the battery sensor and associated wiring.
This code has been associated with vehicles using advanced battery management systems, particularly in models with start-stop technology.
Moderate – While the vehicle may still operate, ignoring this issue could lead to battery management problems.
Driving with a malfunctioning battery sensor could lead to unexpected vehicle shutdowns. Address the issue promptly to ensure safety.
• Vehicle ignition in the 'On' position
• Battery sensor connected
The battery sensor is typically located near the battery, often integrated into the battery terminal or housing.
Q: Can I drive my car with a P15CE code?
A: It's possible to drive, but it's not recommended as it could lead to further battery issues.
Q: How do I reset the P15CE code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, the code will return.
