Right Front Wheel Speed Sensor Performance
A fault with the right front wheel speed sensor has been detected.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The right front wheel speed sensor is not sending proper information about how fast that wheel is turning, which affects traction control and ABS performance.
What the computer is actually seeing
The ABS module monitors the wheel speed sensor data, looking for voltages typically between 0.5 to 3 volts during normal operation. If the signal is inconsistent or out of range, a fault code is triggered.
What a healthy reading looks like
Right front wheel speed should match the other wheels within 5% during movement; voltage readings should be stable at around 1-2 volts when the vehicle is moving.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the wiring and connectors at the right front wheel speed sensor for damage or corrosion. Repair any issues found. If the wiring and connector are fine, proceed to step 2.
- 22. Measure the output voltage of the right front wheel speed sensor with a multimeter while spinning the wheel. You should see a stable voltage between 0.5 to 3 volts. If the voltage is outside this range, replace the wheel speed sensor. If the voltage is within range, proceed to step 3.
- 33. Check the tone ring for damage or missing teeth. If the tone ring is broken or misaligned, replace it. If the tone ring is intact, proceed to step 4.
- 44. Clear the code and test drive the vehicle to see if the code returns. If it does, further diagnosis may be needed on the ABS module.
Common causes
- Damaged wheel speed sensor
- Faulty wiring or connectors
- Broken tone ring on the wheel hub
- ABS module malfunction
- Corrosion in the connector pins

Frequently asked questions
Is it safe to drive with this code?
It's not recommended as it may affect traction control and ABS functionality, potentially leading to loss of control in slippery conditions.
Will this code come back after clearing?
If the underlying issue isn't fixed, it's likely the code will return after driving.
Why does this code pair with others?
It's common for multiple wheel speed sensor codes to trigger together, reflecting similar underlying issues with the ABS system.
