Wheel Speed Sensor Circuit Fail - Front Right
Indicates a fault in 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 isn't getting the right information from the front right wheel speed sensor, which helps it know how fast each wheel is turning.
What the computer is actually seeing
The ABS module expects a voltage signal from the front right wheel speed sensor, typically around 0-5 volts. If the voltage is too low (near 0V or fluctuating), it triggers a fault code.
What a healthy reading looks like
Expected voltage from the sensor should vary between 0.5V to 4.5V while the vehicle is in motion.
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 wiring and connectors at the front right wheel speed sensor for damage or corrosion. Decision: Is there visible damage? If YES, repair the wiring or replace the connector. If NO, proceed to the next step.
- 2Check the resistance of the wheel speed sensor using a multimeter. Expected resistance should be between 1kΩ to 2kΩ. Decision: Is the resistance within this range? If NO, replace the wheel speed sensor. If YES, proceed to the next step.
- 3Disconnect the sensor and check the voltage at the connector with the ignition on (engine off). Expect to see battery voltage (around 12V). Decision: Is there voltage present? If NO, check continuity and integrity of wires from the ABS module to the sensor. If YES, proceed to the next step.
- 4Reinstall the sensor and check for any DTCs after a short test drive. Decision: Is the code still present? If YES, further diagnose the ABS module. If NO, the issue is resolved.
Common causes
- Damaged wheel speed sensor
- Faulty wiring or connector issues
- Corroded terminals
- Absence of signal due to ripped speed sensor ring

Frequently asked questions
Is it safe to drive with this code?
Moderate severity means you can drive but should fix it soon, especially if ABS is affected.
Will this code come back after clearing?
If the underlying problem isn't fixed, the code will likely return.
Why is it only for the front right sensor?
Each wheel has its own sensor; faults can occur individually, affecting only that wheel.
