ABS Wheel Speed Sensor Right Front Circuit Failure
This code indicates a problem with the right front ABS 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 right front wheel speed sensor is not sending signals properly to the ABS module, meaning the ABS system can't monitor wheel speed. This can affect braking performance, especially under hard braking or slippery conditions.
What the computer is actually seeing
The ABS control module looks for voltage and signal frequency from the right front wheel speed sensor. It expects a regular voltage signal that changes as the wheel turns. If it sees a drop in voltage or no signal at all, it triggers this code.
What a healthy reading looks like
The wheel speed sensor should output a signal voltage between 0.5V and 1.5V when the wheel is stationary, and between 0.6V and 5V while moving, depending on vehicle 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.
- 1Inspect the wiring and connectors to the right front wheel speed sensor for damage or corrosion. Check that the connections are secure.
- 2Measure the voltage at the right front wheel speed sensor connector. You should see between 0.5V to 1.5V (at rest) and varying voltages (0.6V to 5V) while the vehicle is in motion. If there's no voltage, go to step 3.
- 3Test the wheel speed sensor by unplugging it and measuring resistance across the sensor terminals. Most should be around 1,000-2,500 ohms. If out of spec, replace the sensor.
- 4Check the tone ring on the right front wheel for damage. There should be no broken or missing teeth. If faulty, replace the tone ring.
- 5If all components check out, consider testing or replacing the ABS control module.
Common causes
- Damaged wheel speed sensor wiring
- Faulty wheel speed sensor
- Corrosion in the connector or at the sensor
- Faulty ABS control module
- Broken teeth on the tone ring

Frequently asked questions
Is it safe to drive with this code?
It’s not recommended, as it affects braking performance and could lead to loss of ABS functionality.
Will the light come back after I clear the code?
If the issue persists or is not resolved, the code may return.
Why does this code sometimes pair with other ABS codes?
Issues in the ABS system can be interconnected; a failure in one sensor can cause others to malfunction.
