This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the sensor that measures the temperature of the battery. It's like when a thermometer isn't working right and you can't tell how hot or cold it is.
The P0515 code indicates that there is an issue with the circuit that connects to the battery temperature sensor. This sensor helps the car manage the battery's charging and performance by monitoring its temperature.
The battery temperature sensor is a crucial component that monitors the temperature of the battery. It ensures that the battery operates within safe temperature limits. If the sensor or its circuit fails, the vehicle's charging system may not function properly, potentially leading to battery damage or reduced performance.
• Check Engine Light is on
• Battery charging issues
• Poor battery performance
• Faulty battery temperature sensor
• Damaged or corroded wiring or connectors
• Faulty powertrain control module (PCM)
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the battery temperature sensor for proper function.
• Replace the battery temperature sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Camry
• Honda Accord
• Ford F-150
• Regularly inspect battery connections and wiring.
• Ensure the battery is properly maintained.
• Check for corrosion and clean battery terminals.
Sensor Issue
• Visit a mechanic if the Check Engine Light is on.
• Avoid long trips until the issue is resolved.
Check with the vehicle manufacturer for specific warranty coverage on electrical components.
This code has been associated with vehicles that have older battery systems or have been exposed to extreme temperatures.
Moderate – It should be addressed soon to prevent battery damage.
Driving with a malfunctioning battery sensor can lead to battery failure, which may leave you stranded.
• Engine running
• Battery fully charged
The battery temperature sensor is typically located near the battery or integrated into the battery itself.
Q: Can I drive with a P0515 code?
A: It's possible to drive, but it's not recommended as it can lead to battery issues.
Q: How do I know if my battery temperature sensor is bad?
A: Symptoms include a Check Engine Light, charging issues, and poor battery performance.
