This summary uses the existing diagnostic information shown in full below.
The car's computer thinks there's a problem with the sensor that measures how hard you're pressing the brake pedal.
The C0650 code indicates an issue with the brake pressure sensor's range or performance. This sensor helps the car's computer understand how much pressure is being applied to the brakes.
The Brake Pressure Sensor N is responsible for monitoring the hydraulic pressure in the braking system. If the sensor's readings are out of the expected range or its performance is inconsistent, the C0650 code is triggered. This could affect the vehicle's braking system and safety features like ABS.
• ABS warning light on
• Brake warning light on
• Reduced braking performance
• Faulty brake pressure sensor
• Wiring issues or poor electrical connections
• Malfunctioning ABS control module
OBD-II: On-Board Diagnostics, a standardized system in vehicles for self-diagnosing and reporting
ABS: Anti-lock Braking System, a safety system that prevents the wheels from locking up during braking
• Use an OBD-II scanner to confirm the code.
• Inspect the brake pressure sensor and its wiring for damage.
• Test the sensor's output with a multimeter.
• Replace the brake pressure sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ABS control module if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

• Cadillac Escalade
• Regularly check brake system components.
• Ensure electrical connections are secure.
• Perform routine vehicle maintenance.
Sensor Issue
• Do not ignore the warning lights on the dashboard.
• Have the brakes checked by a professional if you notice any issues.
• Regular maintenance can prevent sensor failures.
Check with the vehicle manufacturer for warranty coverage on brake system components.
This code has been reported in vehicles with aging brake systems or those exposed to harsh conditions.
High – Brake system issues should be addressed immediately to ensure vehicle safety.
Driving with a malfunctioning brake system can lead to accidents and legal liabilities.
• Vehicle stationary
• Engine running
The brake pressure sensor is typically located near the master cylinder or integrated into the ABS module.
Q: Can I drive with a C0650 code?
A: It's not recommended to drive with this code active, as it can affect braking performance.
Q: How can I reset the C0650 code?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
