This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks there's a problem with the sensor that checks the pressure in the brake booster. It's like when you have a balloon and you can't tell how much air is inside because the gauge isn't working.
The vehicle's computer has detected a low voltage signal from the brake booster pressure sensor circuit, indicating a potential issue with the sensor or its wiring.
The C1014 code is triggered when the brake booster pressure sensor sends a signal that is below the expected range. This could be due to a faulty sensor, damaged wiring, or a problem with the sensor's connection to the vehicle's control module.
• Illuminated check engine light
• Reduced braking performance
• Increased brake pedal effort
• Faulty brake booster pressure sensor
• Damaged or corroded wiring/connectors
• Faulty brake booster
Brake Booster: A device that uses vacuum or hydraulic pressure to assist in applying the brakes.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Use an OBD-II scanner to confirm the C1014 code.
• Inspect the brake booster pressure sensor and its wiring for damage.
• Test the sensor with a multimeter to check for proper voltage and resistance.
• Replace the brake booster pressure sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Replace the brake booster if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

• Regularly inspect brake system components.
• Ensure proper maintenance of electrical connections.
• Replace brake fluid as recommended by the manufacturer.
Sensor Issue
• Do not ignore the check engine light.
• Have the brake system inspected by a professional if you notice any changes in braking performance.
Check with your vehicle manufacturer for specific warranty coverage related to brake system components.
This code has been associated with issues in vehicles that have electronic brake systems, particularly in models with advanced driver-assistance systems.
High – Brake system issues can affect vehicle safety and should be addressed promptly.
Driving with a malfunctioning brake system can be dangerous and may violate vehicle safety regulations.
• Vehicle ignition in the ON position
• Brake pedal depressed
The brake booster pressure sensor is typically located near the brake booster, which is usually found on the driver's side of the engine compartment, near the firewall.
Q: Can I drive with a C1014 code?
A: It's not recommended to drive with a C1014 code, as it may indicate a problem with the brake system, which can be dangerous.
Q: How do I reset the C1014 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, the code should not return.
