C0060 DTC: Left Rear Wheel Speed Sensor Circuit Intermittent/Erratic
What Does C0060 Mean?
Diagnostic Trouble Code (DTC) C0060 indicates that the ABS control module has detected an intermittent or erratic signal from the left rear wheel speed sensor circuit. The signal may fluctuate, disappear temporarily, or become inconsistent with the readings from the other wheel speed sensors, reducing the effectiveness of the ABS, Traction Control (TCS), and Electronic Stability Control (ESC) systems.
Symptoms
- ABS warning light illuminated
- Traction Control (TCS) warning light ON
- Electronic Stability Control (ESC) warning
- Unexpected ABS activation during braking
- Traction Control disabled
- Cruise control may stop working on some vehicles
- Intermittent ABS operation
- Additional ABS-related DTCs stored
Common Causes
- Faulty left rear wheel speed sensor
- Intermittent wiring connection
- Loose, corroded, or water-damaged connector
- Broken or damaged wiring harness
- Cracked or rusty tone ring (reluctor ring)
- Excessive wheel bearing play
- Metal debris attached to the magnetic sensor
- Faulty ABS control module (rare)
Typical Diagnostic Flow
How to Diagnose C0060
- Read ABS fault codes using a professional scan tool.
- Monitor live wheel speed data while driving.
- Compare the left rear wheel speed with the other three wheels.
- Move the wiring harness while monitoring live data to identify intermittent faults.
- Inspect the connector for corrosion, moisture, or loose terminals.
- Inspect the tone ring for cracks, rust, or missing teeth.
- Check the wheel bearing for excessive play.
Typical Values
- All wheel speed sensors should report nearly identical speeds during straight-line driving.
- Signal dropouts or unstable readings indicate an intermittent sensor or wiring fault.
- 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 C0060?
Yes. Normal braking remains available, but the ABS, Traction Control, and Stability Control systems may not function correctly until the fault is repaired.
What is the most common cause of C0060?
The most common causes are an intermittent left rear wheel speed sensor, damaged wiring, loose connectors, a cracked tone ring, excessive wheel bearing play, or metal debris on the sensor.
Will clearing the DTC permanently fix C0060?
No. Clearing the code only removes it temporarily. If the intermittent signal fault remains, the ABS control module will detect the fault again during the next drive cycle.
