Wheel Speed Sensor - 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 measures how fast the wheel is turning. If this sensor fails, the computer can't see if the wheel is spinning correctly, which affects things like ABS and traction control.
What the computer is actually seeing
The engine control module (ECM) looks for a signal from the right front wheel speed sensor that should fluctuate between 0-12 volts as the vehicle moves. If it sees a constant voltage (like 0 volts or 12 volts) when the car is moving, it sets this code.
What a healthy reading looks like
The right front wheel speed sensor should output a signal between 0 to 12 volts, with a typical frequency of 1-15 Hz when the vehicle is moving. If the voltage is static or missing, the sensor may be faulty.
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 for the right front wheel speed sensor for any visible damage or corrosion. Decision point: If damaged, repair or replace the wiring/connector.
- 22. Using a multimeter, test the voltage output of the right front wheel speed sensor with the vehicle in motion. Expected result: 0-12 volts while the car is moving. Decision point: If no voltage or static voltage, suspect sensor failure.
- 33. Check the sensor's physical position and alignment; it should sit correctly in the hub/bearing assembly. Decision point: If misaligned, correct the position and test again; if aligned but still fails, replace the sensor.
- 44. If all checks pass, check the vehicle's ABS and traction control system for other fault codes or issues that could be affecting sensor performance.
Common causes
- Faulty right front wheel speed sensor
- Damaged wiring or connectors to the sensor
- Corrosion at the sensor connector
- Wheel bearing failure causing sensor misalignment

Frequently asked questions
Is it safe to drive with this code?
You can drive the vehicle, but the ABS and traction control systems may not work, which can reduce safety, especially in slippery conditions.
Will this code come back after clearing it?
It can come back if the underlying issue isn't fixed, like a faulty sensor or damaged wiring.
Why does this code sometimes pair with other codes?
Multiple codes can point to issues in the same system, like a failure in the ABS system or related wheel speed sensors.
