Wheel Speed Sensor Circuit Malfunction
This code indicates a problem 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 tells the computer how fast each wheel is spinning. If it stops working or sends bad data, the computer can’t tell if the wheels are slipping or working properly, which can lead to stability control problems.
What the computer is actually seeing
The computer sees voltages that are outside the normal range for the wheel speed sensor circuit. This may include open circuits, short circuits, or a signal that doesn’t match expected patterns.
What a healthy reading looks like
Operating voltage for a wheel speed sensor should be around 5 volts, with output signals varying based on wheel speed, usually between 0-4 volts.
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 wiring and connectors for damage or corrosion. Repair or clean as necessary. Decision Point: Is wiring intact? (Yes/No)
- 2If wiring is good, measure the sensor's output voltage while the wheel is spinning. Expected output is between 0-4 volts. Decision Point: Is output voltage within range? (Yes/No)
- 3If output voltage is not correct, replace the wheel speed sensor. Decision Point: Did replacing the sensor fix the issue? (Yes/No)
- 4If the issue persists, check the ABS control module for faults. Decision Point: Is the ABS module functioning correctly? (Yes/No)
Common causes
- Damaged wiring or connectors for the wheel speed sensor
- Faulty wheel speed sensor
- Corrosion or dirt buildup at the sensor connector
- Issues with the ABS control module

Frequently asked questions
Is it safe to drive with this code?
Driving with this code can affect traction control and stability. It's advisable to fix it soon.
Will the code come back after repairs?
If the repairs are done correctly and the underlying issue is resolved, the code should not return.
Why does this code sometimes pair with ABS codes?
Wheel speed sensors are critical for ABS operation, so faulty sensors can trigger related ABS codes.
