Wheel Speed Sensor - Right Front
Right front wheel speed sensor performance issue 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 computer is getting strange readings from the right front wheel speed sensor, which helps track how fast that wheel is turning compared to the others.
What the computer is actually seeing
The ABS module expects a certain voltage signal from the wheel speed sensor (around 0-5 volts). If it sees a voltage that doesn't match its expected range, it throws this code.
What a healthy reading looks like
Voltage from the wheel speed sensor should be between 0.5 and 4.5 volts when the vehicle is moving. Stationary, it should be close to 0 volts.
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. Check the wiring and connector at the right front wheel speed sensor for any damage or corrosion. If damaged, repair or replace as necessary.
- 22. Verify the wheel speed sensor signal. Use a multimeter to check the voltage output of the sensor while spinning the wheel. You should see a voltage between 0.5 and 4.5 volts. If not, replace the sensor.
- 33. Confirm there are no obstructions like debris or moisture affecting the sensor. Clean or replace if necessary.
- 44. Clear the code and take the vehicle for a test drive. Monitor for reoccurrence of the fault. If the code returns, consider replacing the ABS control module.
Common causes
- Damaged wiring or connectors to the wheel speed sensor.
- Faulty wheel speed sensor.
- Moisture or debris in the connector or sensor.

Frequently asked questions
Is it safe to drive with this code?
It's drivable, but expect potential issues with ABS and traction control systems.
Will the code come back after clearing it?
It may, especially if there's an underlying issue with the sensor or wiring.
Why does this code appear with others like C022A?
They may indicate issues with other wheel speed sensors or related ABS faults.
