This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the sensor that checks the temperature of the brake booster. It's like the car's brain is getting confusing signals about how hot the brake booster is.
The P25C5 code is triggered when the Engine Control Module (ECM) detects a problem with the range or performance of the brake booster temperature sensor circuit.
The brake booster temperature sensor monitors the temperature of the brake booster to ensure it operates within safe parameters. If the sensor's readings are outside the expected range or performance, the ECM sets the P25C5 code.
• Illuminated check engine light
• Reduced braking performance
• Unusual brake pedal feel

Sensor Issue
• Do not ignore the check engine light.
• Get the brake system inspected by a professional.
• Avoid driving aggressively until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on brake system components.
This code has been reported in vehicles with high mileage or those that have experienced electrical issues.
Moderate – While the vehicle may still be drivable, addressing this issue promptly is important for safe braking performance.
Driving with a malfunctioning brake system can be dangerous. Ensure repairs are conducted by a qualified professional.
• Engine running
• Vehicle stationary
The brake booster temperature sensor is typically located near the brake booster assembly, often in the engine bay.
Q: Can I drive with a P25C5 code?
A: It's not recommended to drive with this code as it can affect braking performance. Get it checked as soon as possible.
Q: How can I reset the P25C5 code?
A: After repairs, you can reset the code using an OBD-II scanner. If the problem persists, the code will reappear.
