Wheel Speed Sensor Circuit Malfunction
There's a fault in the wheel speed sensor circuit for one of the wheels.
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 sends signals about how fast each wheel is spinning. When the circuit has a problem—like a broken wire—the car can't see those speeds correctly.
What the computer is actually seeing
The ABS control module detects inconsistencies or no signal from the wheel speed sensor, which it expects to see values rapidly changing as the wheel rotates.
What a healthy reading looks like
Typically, the wheel speed sensor should report values ranging between 0 to 60 Hz while driving; if the vehicle is stationary, the output should be close to 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. Check the wheel speed sensor connector and wiring for damage or corrosion. Repair if necessary.
- 22. Using a multimeter, check the resistance of the wheel speed sensor. It should usually be between 800-1200 ohms. Replace the sensor if out of range.
- 33. With the vehicle in the air, rotate the wheel and observe the signal with a scan tool. Ensure the wheel speed data changes accordingly. If not, replace the sensor.
- 44. Verify the ABS module is receiving a functional signal by checking the input/output data with a scan tool. If the module is unresponsive but the wiring/sensor is good, consider replacing the ABS module.
Common causes
- Broken or damaged wheel speed sensor
- Wiring issues (short, open, corrosion) in the sensor circuit
- Faulty ABS module
- Incorrect installation or replacement of the sensor
