This summary uses the existing diagnostic information shown in full below.
The car's computer is confused because it got a strange reading from the sensor that checks how hard you're pressing the brakes.
The vehicle's computer system has detected an unusual or unexpected reading from the brake booster pressure sensor related to its temperature.
The C1024 code indicates that the brake booster pressure sensor is reporting a temperature value that is not plausible, meaning it is outside the expected range of operation. This could be due to a sensor malfunction, wiring issues, or a problem with the brake booster itself.
• Brake warning light on the dashboard
• Reduced braking performance
• Unusual brake pedal feel
• Faulty brake booster pressure sensor
• Damaged or corroded wiring/connectors
• Malfunctioning brake booster
Brake Booster: A device that increases the force applied to the brake pedal, making it easier to stop the vehicle.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Check for other related codes and clear them.
• Inspect the brake booster pressure sensor and its wiring for damage.
• Test the sensor's output with a multimeter to verify its operation.
• Replace the faulty brake booster pressure sensor.
• Repair or replace damaged wiring/connectors.
• Replace the brake booster if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

• Dodge Ram
• Jeep Grand Cherokee
• Chrysler 300
• Regularly inspect brake system components.
• Ensure proper maintenance of vehicle sensors.
• Avoid exposure of sensors to extreme temperatures.
Sensor Issue
• Do not ignore the brake warning light.
• Get the vehicle inspected by a professional if braking feels different.
Check with your vehicle manufacturer for specific warranty coverage on brake components.
This code has been associated with sensor issues in vehicles with electronic brake systems, particularly in models from the 2000s onward.
High – Braking issues can compromise vehicle safety.
Driving with impaired brakes can be dangerous and may violate vehicle safety regulations.
• Vehicle at operating temperature
• Brakes applied during testing
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.
Q: Can I drive with the C1024 code?
A: It's not recommended to drive with this code active, as it may indicate a brake system issue that could affect safety.
Q: How do I reset the C1024 code?
A: After repairs, use an OBD-II scanner to clear the code. However, ensure the issue is resolved to prevent the code from returning.
