WHEEL SPEED SENSOR 3 PERFORMANCE PROBLEM
There's an issue with the performance of the wheel speed sensor 3.
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 computer is not receiving a proper signal from the third wheel speed sensor, which should send consistent voltage levels that measure the speed of that wheel.
What the computer is actually seeing
The system monitors the wheel speed sensor input, expected to send a signal voltage between 0-5 volts based on the speed of the vehicle. A erratic or missing signal triggers this code.
What a healthy reading looks like
Normal signal from the wheel speed sensor should range between 0 and 5 volts, corresponding to the wheel's rotation speed.
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 connector for wheel speed sensor 3. Look for frays, breaks, or corrosion. Move to step 2 if all is good.
- 22. Check the resistance of the wheel speed sensor circuit. Expected resistance is generally between 1,000 to 2,500 ohms. If outside this range, replace the sensor.
- 33. Monitor the voltage at the wheel speed sensor with a scanner while the vehicle is in operation. Voltage should fluctuate between 0-5 volts as the wheel turns. If not, replace the sensor.
- 44. If replacing the sensor doesn't resolve the issue, check the ABS control module for faults.
Common causes
- Faulty wheel speed sensor 3
- Damaged wiring to the sensor
- Loose or corroded connector
- Sensor signal interference
- ABS control module failure

Frequently asked questions
Is it safe to drive with this code?
It's generally safe, but the ABS won't function properly, so be cautious in slippery conditions.
Will this code come back after clearing?
Yes, if the underlying issue isn't fixed, the code will likely reappear.
Why is this code paired with other wheel speed codes?
They often indicate multiple sensor issues or an overarching ABS control module problem.
