Wheel Speed Sensor Circuit Range/Performance Problem
This code indicates an issue with the 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 wheel speed sensor measures how fast each wheel is turning. If one wheel is reported at an incorrect speed compared to the others, it sets this code. This can give you issues with traction control and ABS.
What the computer is actually seeing
The computer expects a consistent voltage signal related to wheel rotation speed (typical 0-5 volts) from the wheel speed sensor. If the signal is erratic or out of range, it triggers the code.
What a healthy reading looks like
Voltage between 0.5V and 4.5V while the vehicle is moving, with a difference of no more than 10% between each wheel's signal under similar conditions.
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 wiring and connectors at the wheel speed sensor for damage or corrosion. Fix any found issues.
- 22. Measure the voltage at the speed sensor connector while the vehicle is moving. Is it between 0.5V and 4.5V? If yes, go to step 4.
- 33. If voltage is out of range, replace the wheel speed sensor and recheck diagnostics. Is the code gone? If yes, problem solved. If not, go to step 4.
- 44. Use a scan tool to check the readings from all four wheel speed sensors during a test drive. Do all sensors correlate within 10%? If yes, the issue may be in the ABS module. If no, replace the faulty sensor.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connectors
- Debris on the sensor
- Poor ground connection
- Corroded connections

Frequently asked questions
Is it safe to drive with this code?
Drivability may be impaired; traction control and ABS may not function correctly, so fix this soon.
Will this code come back after clearing?
If the underlying problem isn't fixed, it will likely return after the next drive cycle.
Why does this code seem related to the ABS system?
Wheel speed sensors are critical for ABS and traction control; issues can disable those systems.
