Wheel Speed Sensor Incorrect Signal
The wheel speed sensor is sending a signal that doesn’t match expected parameters.
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 should send a signal based on its rotation speed, usually between 0-5 volts. If it sends something odd, like a constant 0 volts or an incorrect frequency, the computer flags it as a problem.
What the computer is actually seeing
The ABS/control module expects a voltage signal that varies with wheel speed. Normal operation shows voltage rising and falling with vehicle speed, typically between 0 to 5 volts as the wheel rotates.
What a healthy reading looks like
0-5 volts corresponding to wheel speed; at rest, expect near 0 volts, while moving expect varying voltage.
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 wiring and connectors to the wheel speed sensor for damage or corrosion. Repair as necessary and retest.
- 22. Measure the voltage at the wheel speed sensor connector. At rest, you should see around 0 volts. During movement, it should vary between 0-5 volts. If you only get 0 volts while moving, proceed to step 3.
- 33. Inspect the reluctor ring for cracks or missing teeth. If it's damaged, replace it and retest.
- 44. If the sensor and ring are good, test the sensor with a multimeter to ensure it meets the specifications—replace if outside the specifications. If still faulty, check the ABS module.
Common causes
- Damaged or corroded wheel speed sensor.
- Faulty wiring or poor connections.
- Damaged reluctor ring or tone ring.
- Faulty ABS module.

Frequently asked questions
Is it safe to drive with this code?
It's drivable, but you may lose ABS function, increasing stopping distance in slippery conditions.
Will this code come back if I clear it?
If the underlying issue isn't fixed, yes, it will likely return.
Why is this appearing alongside other wheel sensor codes?
Common failures usually affect multiple sensors, or it could indicate an issue with the ABS control module.
