Wheel Speed Sensor Malfunction - Right Front
This code indicates a problem with the right front wheel speed sensor.
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 either not sending a signal or the signal it sends is out of range, affecting the anti-lock brake system (ABS) and traction control.
What the computer is actually seeing
The ABS control module expects a voltage signal from the wheel speed sensor that fluctuates between 0 to 12 volts, reflecting the wheel's rotational speed. If the voltage remains constant or drops below 0.5 volts or goes above 12 volts, it triggers this code.
What a healthy reading looks like
Normal operating voltage from the wheel speed sensor should be between 0.5 to 12 volts, depending on wheel speed.
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.
- 1Check the right front wheel speed sensor wiring and connector. Look for frays, corrosion, or loose connections. If any issues are found, repair them and clear the code.
- 2Using a multimeter, measure the voltage at the sensor connector with the key on and the engine running. The voltage should be within the expected values. If it's not, the sensor may be faulty.
- 3Inspect the right front wheel bearing for excessive play or damage that might affect sensor alignment. Shake the wheel to check for play.
- 4If the sensor and wiring are good, check the ABS control module for faults. Use a scan tool to see if other related codes appear. If the module is faulty, it may need to be replaced.
Common causes
- Faulty right front wheel speed sensor
- Damaged wiring or connectors in the sensor circuit
- Wheel bearing issues affecting sensor alignment
- Faulty ABS control module
Typical repair cost
$$$ - $$$$

Frequently asked questions
Is it safe to drive with this code active?
It's recommended to get this fixed soon, as ABS and traction control will not function properly, affecting braking performance.
Will this code come back after clearing it?
If the underlying issue isn't fixed, like a bad sensor or wiring problem, the code will likely return.
Why does this code often pair with others?
Many ABS-related codes can trigger simultaneously due to shared components or systemic failures.
