Wheel Speed Sensor Intermittent
There’s an intermittent issue 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 computer is having trouble consistently reading the speed of one of the wheels due to a possible sensor or wiring issue.
What the computer is actually seeing
The vehicle's computer expects a steady voltage signal from the wheel speed sensor, typically around 0-5 volts, which fluctuates based on wheel rotation. Intermittent drops or spikes indicate a problem.
What a healthy reading looks like
Normal operation shows wheel speeds matching vehicle speed, typically ranging from 0 to 255 mph depending on the sensor's design and conditions.
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 wheel speed sensor wiring and connectors for damage or corrosion. If any issues found, repair or replace as necessary.
- 22. Check the wiring harness for continuity between the sensor and the ABS module. A good reading should show little to no resistance, typically less than 5 ohms. If resistance is higher, repair the harness.
- 33. Verify that the wheel speed sensor is clean and free of debris. Clean it with a soft cloth if dirty. If issues persist after cleaning, consider replacing the sensor.
- 44. Use a scan tool to simulate wheel speed and observe the data. If the sensor data behaves erratically during testing, replace the wheel speed sensor.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connectors
- Dirty sensor or reluctor ring
- Faulty ABS module

Frequently asked questions
Is it safe to drive with this code?
It may be drivable, but expect potential issues with traction control and ABS, which can affect safety.
Will this code come back after being cleared?
If the underlying problem isn't fixed, yes, it likely will return.
Why is it paired with other codes?
It commonly coincides with other sensor or control module-related codes due to shared wiring or system functionality.
