Causes

  • Damaged or failed rear-right wheel speed sensor
  • Open, shorted or corroded wiring/connectors to the sensor
  • Missing/damaged tone ring (reluctor) or magnetic debris on tone ring
  • Wheel bearing or hub damage affecting sensor gap/alignment
  • Water/contaminants on sensor or connector
  • Faulty ABS/ESC control module or poor ground

Symptoms

  • ABS warning lamp illuminated (often with ESC/Traction control lamp)
  • Traction control and/or stability control disabled
  • ABS may activate incorrectly or not when expected
  • ABS/ESC fault messages in cluster or reduced braking/stability function
  • Possible inconsistent wheel speed reading on scan tool for rear-right wheel

What to check

  • Use a scan tool to read freeze frame and all stored ABS/ESC codes and live wheel speed data
  • Visually inspect rear-right sensor, connector and wiring for damage, corrosion, chafing or pinched sections
  • Inspect tone ring/reluctor on hub/axle for missing teeth, cracks or heavy contamination
  • Raise vehicle safely and spin rear-right wheel while watching live wheel-speed values on a scan tool
  • Back-probe sensor connector to check for reference/supply voltage (if active sensor) and signal waveform with oscilloscope or lab scope
  • Check connector pins for corrosion/bend and apply dielectric grease after repairs

Signal parameters

  • Wheel speed sensors produce a pulsed signal proportional to wheel speed. Signal type depends on sensor design: passive (VR) = AC sine/AC voltage; active (Hall/electronic) = pulsed/square wave referenced to supply (typically 0–5V)
  • At rest: signal should be steady/zero. When wheel rotates: signal frequency and amplitude increase with speed
  • No signal or irregular pulses at low speeds indicates open/shorted sensor, wrong air gap, damaged tone ring, or contamination
  • Intermittent or noisy signal (dropouts, irregular amplitude) suggests wiring intermittent, poor ground, or sensor failing
  • Supply/reference: active sensors typically have a reference/supply, signal and ground; verify correct reference voltage with ignition on

Diagnostic algorithm

  1. Retrieve codes and live data with a diagnostic scan tool; note any additional ABS/ESC codes.
  2. Perform a visual inspection of the rear-right sensor, connector and wiring from the sensor to the ABS module; repair obvious damage and clean connectors.
  3. Safely lift the vehicle and secure on stands. Rotate the rear-right wheel by hand while observing wheel-speed values on the scan tool. Compare to other wheels.
  4. If no/erratic signal: back-probe the sensor connector. For active sensors check reference voltage and ground; for passive sensors check for AC voltage while spinning the wheel. Use an oscilloscope if available to view waveform shape and frequency.
  5. Check resistance/continuity of the sensor circuit to the ABS module; check for shorts to chassis. Repair wiring faults before replacing the sensor.
  6. Inspect tone ring/reluctor and hub/bearing for damage, missing teeth or magnetic debris and correct as needed. Verify proper sensor-to-reluctor air gap and sensor mounting.
  7. If wiring and tone ring are good, swap the suspect sensor with a known-good sensor (if identical) or replace the sensor and retest.
  8. Clear codes after repairs and perform a test drive to confirm the fault does not return. If fault persists with good sensor/wiring, consider ABS/ESC module inspection or professional diagnosis.

Likely causes

  • Sensor wiring harness rubbed or pinched at suspension joint
  • Connector corrosion or bent pins at the sensor or module
  • Sensor air gap too large due to bent mounting bracket or damaged tone ring
  • Sensor magnet or element failed from impact or contamination
  • Intermittent open circuit caused by flexing harness

Fault status

⚠️ Status
ABS/ESC fault: Sensor 4 (rear-right wheel speed sensor) malfunction detected. Check sensor, wiring, tone ring and ABS control module.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2 hours
