Wheel Speed Sensor Signal Error
There's a problem with the wheel speed sensor signal.
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 it sends a faulty signal to the computer, it can't accurately determine wheel speed for traction control or ABS systems.
What the computer is actually seeing
The vehicle's computer sees inconsistent or missing signals from the wheel speed sensor, which may appear as erratic voltage levels or constant zero readings where normally it should fluctuate based on wheel speed.
What a healthy reading looks like
Typically, a functioning wheel speed sensor outputs a voltage between 0.5V to 2.5V depending on wheel speed; at rest it should be close to 0V.
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 connectors at the wheel speed sensor; look for damage or corrosion. If found, repair or replace the connector/wiring.
- 22. Check the output voltage of the wheel speed sensor with a multimeter while spinning the wheel; it should have a varying voltage output in normal conditions. If voltage is incorrect, replace the sensor.
- 33. Verify if any tire size changes have been made recently. If tires are mismatched, correct perimeter must be recalibrated to the ABS system.
- 44. Clear the code and test drive the vehicle to see if the code returns. If it does, you may have a fault in the ABS module.
Common causes
- Damaged or corroded wiring
- Faulty wheel speed sensor
- Bad connector at the sensor
- Issues with the ABS module
- Incorrect wheel circumference due to tire size changes

Frequently asked questions
Is it safe to drive with this code?
It's generally unsafe to drive with a faulty wheel speed sensor because it can impact ABS and traction control. It’s best to diagnose and fix it soon.
Will this code come back after I clear it?
If the underlying issue isn’t resolved, yes, the code will likely return after some driving.
Why do I only see this code on one wheel?
Wheel speed sensors operate individually for each wheel; if one fails, you’ll only see a code for that specific wheel.
