C0006 Code – Right Front Wheel Speed Sensor Circuit

The C0006 Diagnostic Trouble Code (DTC) indicates that the Anti-lock Braking System (ABS) module has detected a malfunction in the right front Wheel Speed Sensor (WSS) circuit. The wheel speed sensor continuously monitors wheel rotation and sends this information to the ABS module to support ABS, Traction Control (TCS), and Electronic Stability Control (ESC) operation.

What Does C0006 Mean?

C0006 means the ABS control module has received an abnormal signal or detected an electrical fault from the right front wheel speed sensor circuit. The problem may involve an open circuit, short circuit, weak signal, excessive sensor gap, or a damaged reluctor (tone) ring.

Symptoms of C0006

• ABS warning light illuminated.
• Traction Control (TCS) warning light on.
• Electronic Stability Control (ESC) warning light illuminated.
• ABS system disabled.
• Traction control unavailable.
• Reduced stability control performance.
• In some vehicles, an inaccurate speedometer reading.

Common Causes

• Faulty right front Wheel Speed Sensor (WSS).
• Damaged or broken sensor wiring.
• Loose or corroded electrical connector.
• Metal debris on the magnetic sensor tip.
• Cracked or damaged reluctor (tone) ring.
• Excessive wheel bearing play affecting the sensor gap.
• Faulty ABS control module (rare).

How to Diagnose C0006

1. Retrieve ABS fault codes with a professional scan tool.
2. Compare live wheel speed data from all four wheels.
3. Inspect the right front sensor and wiring harness.
4. Clean the sensor if contaminated with metal particles.
5. Inspect the reluctor ring for cracks, rust, or missing teeth.
6. Check the wheel bearing for excessive play.
7. Measure sensor resistance and circuit continuity.

How to Fix C0006

• Replace the faulty Wheel Speed Sensor (WSS).
• Repair damaged wiring or electrical connectors.
• Clean the sensor tip.
• Replace the damaged reluctor ring.
• Replace the wheel bearing if excessive movement is present.
• Replace the ABS control module only after confirming all other components are functioning correctly.

Can You Drive With C0006?

Yes, the vehicle can usually still be driven because standard braking remains operational. However, the ABS, Traction Control, and Electronic Stability Control systems may be disabled, reducing safety during emergency braking or while driving on wet, icy, or loose surfaces.

Repair Cost Estimate

Repair	Estimated Cost (USD)
Wheel Speed Sensor replacement	$80–$250
Wiring repair	$50–$200
Reluctor ring replacement	$100–$350
Wheel bearing replacement	$200–$600

Frequently Asked Questions

What causes C0006?

The most common causes are a failed wheel speed sensor, damaged wiring, a dirty sensor tip, or a damaged reluctor ring.

Can a bad wheel bearing trigger C0006?

Yes. Excessive wheel bearing play can increase the air gap between the sensor and reluctor ring, producing an incorrect wheel speed signal.

Will clearing the code permanently fix C0006?

No. Clearing the code only removes it temporarily. If the root cause is not repaired, the ABS module will detect the fault again and the code will return.

Conclusion

C0006 indicates a fault in the right front Wheel Speed Sensor circuit. A thorough inspection of the sensor, wiring, reluctor ring, and wheel bearing will usually identify the cause. Repairing the problem restores proper ABS, traction control, and electronic stability control operation.
