• C0515
• C0517
This code means that the car's computer is having trouble getting a steady reading from the sensor that checks how fast the right rear wheel is spinning. It's like trying to listen to a radio station with a lot of static.
The wheel speed sensor sends information about the wheel's speed to the car's computer. If the signal is erratic, it can affect systems like ABS.
The C0516 code indicates that the right rear wheel speed sensor is sending an intermittent or erratic signal to the vehicle's control module. This can affect the vehicle's anti-lock braking system (ABS) and traction control system, as these rely on accurate wheel speed data.
• Inspect the right rear wheel speed sensor for damage or debris.
• Check the wiring and connectors for signs of wear or damage.
• Use a multimeter to test the sensor's output signal.
• Clean the sensor and tone ring.
• Repair or replace damaged wiring or connectors.
• Replace the wheel speed sensor if faulty.

Check with the vehicle manufacturer for warranty coverage on ABS components.
This code has been commonly reported in vehicles with high mileage or those frequently driven in harsh conditions.
Moderate – While the vehicle can still be driven, the ABS system may not function properly, affecting braking safety.
Driving with a malfunctioning ABS system can increase the risk of accidents. Ensure repairs are made promptly.
• Vehicle must be driven at a steady speed.
• Ensure the ABS warning light is illuminated.
The right rear wheel speed sensor is located near the wheel hub assembly on the rear passenger side of the vehicle.
Q: Can I drive with a C0516 code?
A: You can drive, but it's not recommended as the ABS may not work properly, affecting your ability to stop safely.
Q: How do I reset the ABS light after fixing the issue?
A: Use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes to reset the system.
