C0580 — Right Rear Wheel Speed Sensor Signal Out of Range

Severity: medium Drive with care, to a shop

What C0580 means

The ABS/ESC control unit constantly compares the speed signals from all four wheels. C0580 is set when the right rear sensor's signal is outside a plausible range or disagrees with the other wheels. The sensor reads pulses from a toothed tone ring on the hub, and if that signal is distorted the system cannot reliably detect wheel slip.

Symptoms

  • ABS warning light on
  • ESC/traction control light on or flashing
  • Stability and traction control disabled
  • Wheels lock up under hard braking
  • Erratic speedometer reading (rare)
  • Code returns after clearing

Possible causes

  1. Failed right rear wheel speed sensor
  2. Damaged, rusty or out-of-true tone ring
  3. Sensor tip contaminated with metal debris and dirt
  4. Mismatched tire sizes or very uneven tire wear
  5. Excess sensor air gap from a worn wheel bearing
  6. Damaged wiring or connector at the sensor

How to diagnose

  1. Scan all ABS codes and view live data for each wheel's speed
  2. Compare the right rear speed with the other wheels at a steady speed
  3. Inspect the sensor, connector and wiring for breaks, corrosion or rubbing
  4. Remove the sensor and clean its tip of dirt and metal debris
  5. Inspect the tone ring for cracks, missing teeth, rust or runout
  6. Check wheel bearing play and sensor mounting and air gap
  7. Confirm all tires are the same size and properly inflated
  8. Test the sensor resistance or view its signal on a scope while spinning the wheel

Common fixes

  • Clean the sensor and its bore
  • Replace the right rear wheel speed sensor
  • Replace the hub bearing or tone ring
  • Repair the wiring or connector
  • Match tire sizes and set correct pressures

Questions and answers

Can I drive with a C0580 code?

Yes, but carefully and not for long. Normal brakes work, yet ABS and ESC are likely off, so stopping distance and skid risk go up on wet roads.

What most often causes C0580?

Usually a dirty or failed sensor, a damaged tone ring, or wiring damage. Mismatched tire sizes can also trigger it.

Is clearing the code enough?

No. If the cause remains, the code will return after a drive. Find and fix the fault first, then clear the code.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
