Wheel Speed Sensor Right Front
Fault in the right front 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 monitors the speed of each wheel to manage anti-lock brakes and traction control. If the right front sensor sends faulty data, it can cause safety features to malfunction.
What the computer is actually seeing
The ABS control module expects a consistent voltage signal ranging from 0 to 5 volts as the wheel turns. If this signal fluctuates too much or goes below 0 volts or above 5 volts, the module registers a fault.
What a healthy reading looks like
Expected voltage varies between 0.5 to 4.5 volts while driving, depending on wheel 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.
- 1Check the right front wheel speed sensor wiring and connector for damage or corrosion. Fix any issues found.
- 2Measure the voltage at the wheel speed sensor connector with the key on, engine off. Expected voltage should be near battery voltage (12V). If not, repair wiring.
- 3With the vehicle in motion, check the voltage output of the right front wheel speed sensor. It should fluctuate between 0.5 to 4.5 volts. If not, replace the sensor.
- 4Perform a scan of the ABS module for any additional fault codes that may provide more context about the issue.
Common causes
- Damaged right front wheel speed sensor
- Wiring issues in the sensor circuit
- Connector corrosion or damage
- Faulty ABS control module
