C0041 DTC: Right Front Wheel Speed Sensor Circuit Range/Performance
What Does C0041 Mean?
Diagnostic Trouble Code (DTC) C0041 indicates that the ABS control module has detected that the right front wheel speed sensor signal is outside the expected operating range or its performance is abnormal. The sensor may still produce a signal, but it is inaccurate, intermittent, or inconsistent with the speed of the other wheels.
Symptoms
- ABS warning light illuminated
- Traction Control (TCS) warning light ON
- Electronic Stability Control (ESC) disabled
- Unexpected ABS activation during braking
- Reduced traction control performance
- Cruise control may be disabled on some vehicles
- Additional ABS DTCs may be stored
Common Causes
- Faulty right front wheel speed sensor
- Damaged or cracked tone ring (reluctor ring)
- Incorrect sensor air gap
- Wheel bearing wear or excessive play
- Damaged sensor wiring harness
- Loose or corroded connector
- Metal debris attached to a magnetic sensor
- Faulty ABS control module (rare)
Typical Diagnostic Flow
How to Diagnose C0041
- Read ABS DTCs using a professional scan tool.
- Monitor live wheel speed data while driving.
- Compare the right front wheel speed with the remaining wheels.
- Inspect the tone ring for rust, cracks, or missing teeth.
- Verify the sensor air gap is within manufacturer specifications.
- Inspect the wiring harness and connector for damage or corrosion.
- Check the wheel bearing for excessive movement.
Typical Values
- All four wheel speed sensors should display nearly identical speeds during straight-line driving.
- Intermittent or unstable readings indicate a sensor performance problem.
- Specifications vary by vehicle manufacturer.
Estimated Repair Cost
- Wheel speed sensor replacement: $70–250
- Wiring repair: $50–200
- Tone ring replacement: $80–300
- Wheel bearing replacement: $150–500
- ABS module replacement: $400–1,200

Frequently Asked Questions
Can I drive with C0041?
Yes. Normal braking remains available, but the ABS, Traction Control, and Stability Control systems may be disabled until the fault is repaired.
What is the most common cause of C0041?
The most common causes are a faulty right front wheel speed sensor, damaged tone ring, excessive wheel bearing play, or wiring and connector problems.
Will clearing the DTC permanently fix C0041?
No. Clearing the code only removes it temporarily. If the performance problem remains, the ABS module will detect it again during the next drive cycle.
