Wheel Speed Sensor (Front Right) Performance Problem
The front right wheel speed sensor is reporting incorrect data to the control module.
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 could affect traction control and ABS.
What the computer is actually seeing
The control module expects to see a consistent voltage signal from the wheel speed sensor, averaging around 0.5V to 5V based on wheel speed. An outlier or dropped signal indicates a problem.
What a healthy reading looks like
Wheel speed sensors typically output a frequency of 0-4000 Hz depending on vehicle speed; at rest, it should be 0 Hz.
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. Inspect the wiring and connector of the front right wheel speed sensor for any visible damage, corrosion, or loose connections. Decision: Is wiring intact? If no, repair or replace the wiring. If yes, proceed to step 2.
- 22. Measure the voltage at the sensor connector while the vehicle is stationary. Voltage should be within 0.5V to 5V. Decision: Is the voltage reading normal? If no, replace the sensor. If yes, proceed to step 3.
- 33. Check the signal frequency at the sensor with a scan tool while spinning the wheel manually (should match expected values). Decision: Is the signal frequency correct? If no, replace the sensor. If yes, proceed to step 4.
- 44. Inspect the ABS control module for any fault codes or internal failures. Decision: Any related fault codes? If yes, troubleshoot those codes. If all checks are good, consider replacing the ABS module.
Common causes
- Faulty front right wheel speed sensor
- Damaged wiring or connectors to the sensor
- Corrosion or dirt buildup at the sensor
- Issues with the ABS control module

Frequently asked questions
Is it safe to drive with this code?
It's not recommended as it may disable traction control and ABS functions.
Will this code come back after resetting?
If there’s an underlying issue with the sensor or wiring, it likely will.
Why does this code pair with others?
It can be related to the function of the ABS system where multiple sensors monitor wheel speed.
