C0067 DTC: Right Front Wheel Speed Sensor Circuit High
What Does C0067 Mean?
Diagnostic Trouble Code (DTC) C0067 indicates that the ABS control module has detected a higher-than-expected voltage or signal level in the right front wheel speed sensor circuit. This condition is commonly caused by an open circuit, excessive resistance, poor electrical connections, damaged wiring, or a faulty wheel speed sensor. An incorrect signal prevents the ABS module from accurately monitoring wheel speed, which may affect the operation 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.
- ABS may be disabled during emergency braking.
- Traction Control system unavailable.
- Incorrect wheel speed displayed in live data.
- Cruise control may be disabled on some vehicles.
- Additional ABS-related DTCs stored.
Common Causes
- Faulty right front wheel speed sensor.
- Open circuit in the sensor wiring.
- Loose or disconnected electrical connector.
- Corroded connector terminals.
- Damaged wiring harness.
- Damaged tone ring (reluctor ring).
- Excessive wheel bearing play affecting sensor alignment.
- Faulty ABS control module (rare).
Typical Diagnostic Flow
How to Diagnose C0067
- Read ABS trouble codes using a professional scan tool.
- Monitor live wheel speed data during a road test.
- Compare the right front wheel speed with the remaining wheels.
- Inspect the sensor wiring for open circuits or damaged insulation.
- Check the connector for corrosion, bent pins, or loose terminals.
- Measure sensor resistance and circuit voltage.
- Inspect the tone ring and wheel bearing for mechanical damage.
- Repair or replace faulty components and clear the DTC.
Typical Values
- All wheel speed sensors should display nearly identical speeds during normal driving.
- Signal voltage should remain within manufacturer specifications.
- A consistently high circuit voltage usually indicates an open circuit or excessive resistance.
- 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 control module replacement: $400–1,200

Frequently Asked Questions
Can I drive with C0067?
Yes. The vehicle can usually be driven normally, 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 C0067?
The most common causes are an open circuit, damaged wiring, loose or corroded connectors, excessive circuit resistance, or a faulty right front wheel speed sensor.
Will clearing the DTC permanently fix C0067?
No. Clearing the code only erases it temporarily. If the electrical fault remains, the ABS control module will detect the problem again during the next drive cycle.
