Wheel Speed Sensor Front Right Circuit Malfunction
There’s an issue with the front right wheel speed sensor circuit.
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 not getting the right signals from the front right wheel speed sensor, which helps manage things like traction control and anti-lock brakes.
What the computer is actually seeing
The ABS module expects to see a varying voltage output from the wheel speed sensor that correlates with wheel rotation—typically around 0 to 5 volts. If it stays constant or shows no signal, the module sets this code.
What a healthy reading looks like
0-5 volts while rotating; less than 0.5 volts indicates a failure from the sensor or circuit.
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 wiring and connector at the front right wheel speed sensor for damage or corrosion. Repair as necessary.
- 2With the key on, use a multimeter to check the voltage at the connector. Expected voltage is around 0.5 to 5 volts when the wheel is moving. If there is no reading, go to step 3.
- 3Inspect the wheel speed sensor itself. Disconnect the sensor and check resistance. A good sensor should show around 800-1200 ohms. If not, replace the sensor.
- 4If the sensor checks out, scan the ABS system for other codes. If related codes are present, address those first before returning to this code.
- 5If all checks out and the issue persists, consider testing the ABS module, as it could be interpreting the sensor signal incorrectly.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connector to the sensor
- Corrosion in the connector pins
- Faulty ABS module
