ABS: Anti-lock Braking System
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• C0515
• C0561
The car's computer is having trouble reading the speed of the right rear wheel because the sensor is not working properly.
This code indicates that the signal from the right rear wheel speed sensor is lower than expected, which could mean an electrical issue or sensor malfunction.
The C0514 code is triggered when the ABS (Anti-lock Braking System) module detects a low voltage signal from the right rear wheel speed sensor. This sensor is responsible for monitoring the rotational speed of the wheel and sending this information to the ABS module to help control braking performance.
• Inspect the right rear wheel speed sensor for damage.
• Check the wiring and connectors for corrosion or damage.
• Test the sensor's voltage output with a multimeter.
• Replace the right rear wheel speed sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Clean and secure any corroded or loose connections.
• Multimeter
• Socket set
• Jack and jack stands

Sensor Issue
• Have a professional inspect the ABS system if the warning light is on.
• Avoid harsh braking until the issue is resolved.
Check with your vehicle manufacturer for warranty coverage on ABS components.
Wheel speed sensor issues have been common in vehicles with ABS systems, often due to environmental factors affecting the sensors.
Moderate – While the vehicle can still be driven, braking performance may be compromised.
Driving with a malfunctioning ABS system can increase the risk of accidents. It is advisable to address this issue promptly.
• Vehicle stationary
• Ignition on, engine off
The right rear wheel speed sensor is located near the wheel hub of the right rear wheel.
Q: Can I drive with a C0514 code?
A: While you can drive with this code, it's not recommended as it may affect braking performance.
Q: How do I reset the ABS light after fixing the issue?
A: The ABS light should reset itself after the repair. If not, a scan tool may be needed to clear the code.
