Wheel Speed Sensor Performance
Issue detected with one or more wheel speed sensors.
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 vehicle's computer is having trouble understanding the speed at which the wheels are turning, which could affect traction control and ABS operations.
What the computer is actually seeing
The ABS control module receives erratic or low signals (under 0.5 volts or over 5 volts) from one or more wheel speed sensors while the vehicle is in motion.
What a healthy reading looks like
Each wheel speed sensor should generate a voltage signal that fluctuates between 0.5V to 5V as the wheel rotates; speed readings should correspond to vehicle speed and match across all four corners.
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 wiring and connectors for damage or corrosion. If damaged, repair or replace as necessary. Next step is to check sensor output.
- 22. Measure the voltage at each wheel speed sensor connector while the vehicle is in motion. Expected values are fluctuating 0.5V-5V. If a sensor shows no signal, replace the sensor and retest.
- 33. Use a scan tool to check for additional codes related to the ABS or traction control system. Additional codes could help locate a failed component. If no additional codes, proceed to check the reluctor ring.
- 44. Inspect the reluctor ring for cracks or breaks. Replace if damaged. After repairs, clear codes and test drive the vehicle to confirm resolution.
Common causes
- Faulty wheel speed sensor(s)
- Damaged wiring or connectors to wheel speed sensors
- Corrosion in sensor connectors
- Broken reluctor ring on the wheel hub

Frequently asked questions
Is it safe to drive with this code?
It's generally safe to drive, but keep in mind that ABS and traction control may not work correctly. Fix it soon.
Will this code come back after clearing it?
It could return if the underlying issue isn't resolved, such as a faulty sensor or wiring.
Why do I see related codes for other wheel speed sensors?
If one sensor fails, it can cause the system to throw codes for multiple sensors as it looks for corroborating data.
