Wheel Speed Sensor Performance
Indicates a performance issue with the wheel speed sensor.
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 is not giving accurate readings about how fast the wheel is spinning, which helps control braking and traction.
What the computer is actually seeing
The ABS module expects the wheel speed sensor to produce a voltage signal varying between 0.5V (stationary) and 12V (high speed).
What a healthy reading looks like
Wheel speeds expected to be within 0-30 km/h (0-19 mph) at idle or very low speed, with discrepancies noted between wheels beyond 5% variance.
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 for the wheel speed sensor for damage or corrosion. Decision: If damaged, repair or replace the wiring/connectors. If okay, proceed to step 2.
- 22. Measure the voltage output at the wheel speed sensor with the wheel spinning. Expected value is between 0.5V and 12V. Decision: If voltage is within range, proceed to step 3. If not, replace the wheel speed sensor.
- 33. Compare readings from all wheel speed sensors. They should vary by no more than 5%. Decision: If there's too much variance, check for physical damage or misalignment. If all readings are okay, the issue might be in the ABS module.
Common causes
- Wiring issue or connector damaged
- Wheel speed sensor failure
- Faulty brake module
- Contaminated sensor (dirt or debris)

Frequently asked questions
Is it safe to drive with this code?
It's drivable but fix it soon since it affects ABS and traction control.
Will this code come back after repairs?
If the root cause is fixed properly, it shouldn't come back.
Why does it pair with other codes?
Multiple wheel speed sensor issues can present differently but relate to the same system.
