C0516: Right Rear Wheel Speed Sensor A Intermittent/Erratic
Standardized SAE J2012 code · C05xx codes
Safety-critical system. Faults in airbags, brakes, steering or high-voltage components can put people at risk. Follow the manufacturer's service information and safety procedures, or have the vehicle checked by a qualified workshop.
What does C0516 mean?
Intermittent signal from right-rear WSS A. Wheel-speed signals feed ABS, ESC, traction control, transmission and odometer — a single dropped signal disables all of these safety functions until repaired.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
Common causes
- High Connector loose or chafed wiring
- Low Connector with intermittent contact under vibration
- Low Harness routed against vibrating component
