C0062 DTC: Left Rear Wheel Speed Sensor Circuit Range/Performance
What Does C0062 Mean?
Diagnostic Trouble Code (DTC) C0062 indicates that the ABS control module has detected that the left rear wheel speed sensor signal is outside the expected operating range or does not perform consistently with the other wheel speed sensors. Although the circuit may still be electrically functional, inaccurate or unstable sensor data can reduce the effectiveness of the Anti-lock Braking System (ABS), Traction Control System (TCS), and Electronic Stability Control (ESC).
Symptoms
- ABS warning light illuminated
- Traction Control (TCS) warning light ON
- Electronic Stability Control (ESC) warning
- Unexpected ABS activation during braking
- Reduced braking stability on slippery roads
- Traction Control disabled
- Cruise control may be disabled on some vehicles
- Additional ABS-related DTCs stored
Common Causes
- Faulty left rear wheel speed sensor
- Damaged or cracked tone ring (reluctor ring)
- Incorrect sensor air gap
- Excessive wheel bearing play
- Metal debris attached to the magnetic sensor
- Damaged wiring harness
- Loose, corroded, or water-damaged connector
- Faulty ABS control module (rare)
Typical Diagnostic Flow
How to Diagnose C0062
- Read ABS trouble codes using a professional scan tool.
- Monitor live wheel speed data while driving.
- Compare the left rear wheel speed with the remaining wheel speed sensors.
- Inspect the tone ring for cracks, rust, or missing teeth.
- Verify the sensor air gap meets manufacturer specifications.
- Inspect the wheel bearing for excessive movement.
- Check the wiring harness and connector for corrosion, damage, or loose terminals.
- Clean any metal debris from the magnetic sensor.
Typical Values
- All wheel speed sensors should display nearly identical speeds during straight-line driving.
- Unstable or inconsistent readings usually indicate a sensor performance or mechanical problem.
- Actual specifications vary by vehicle manufacturer.
Estimated Repair Cost
- Wheel speed sensor replacement: $70–250
- Wiring repair: $50–200
- Connector replacement: $30–120
- Tone ring replacement: $80–300
- Wheel bearing replacement: $150–500
- ABS module replacement: $400–1,200

Frequently Asked Questions
Can I drive with C0062?
Yes. The vehicle can usually be driven safely, but the ABS, Traction Control, and Stability Control systems may not operate correctly until the underlying fault is repaired.
What is the most common cause of C0062?
The most common causes are a faulty left rear wheel speed sensor, a damaged tone ring, excessive wheel bearing play, metal contamination on the sensor, or damaged wiring and connectors.
Will clearing the DTC permanently fix C0062?
No. Clearing the code only erases it temporarily. If the underlying range or performance problem remains, the ABS control module will detect the fault again during the next drive cycle.
