Wheel Speed Sensor Performance Problem
This code indicates an issue with the wheel speed sensor system.
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 tracks how fast each wheel is turning. If it notices one wheel is spinning differently than the others, it throws this code.
What the computer is actually seeing
The ABS control module detects that the wheel speed sensor readings are inconsistent or outside the expected range.
What a healthy reading looks like
Wheel speed sensors typically send a signal between 0.5V to 5V, depending on the wheel's speed, with typical values between 1V to 3V for normal operation at low speeds.
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 wheel speed sensor wiring and connectors for damage. If found, repair or replace them. DECISION: If wiring/connectors are good, proceed to step 2, else repair.
- 22. Check the resistance of the wheel speed sensor (should be within the manufacturer's specification, typically around 1000-1200 ohms). If out of spec, replace the sensor. DECISION: If in spec, proceed to step 3, else replace the sensor.
- 33. Use a scan tool to monitor wheel speed sensor readings from all wheels while driving. Check for inconsistencies. If a specific sensor shows abnormal readings, replace that sensor. DECISION: If all readings are consistent, further diagnose the ABS module.
Common causes
- Damaged wheel speed sensor
- Faulty wiring or connectors
- ABS module failure
- Incorrectly mounted wheel speed sensor
- Faulty brake system components

Frequently asked questions
Is it safe to drive with this code?
It's not ideal. You'll have reduced traction control and ABS functionality, which can increase stopping distances.
Will this code come back after repairs?
If you fix the root cause, it shouldn't come back, but if it's a wiring issue, ensure all connections are stable.
Why does this code sometimes pair with others?
It often pairs with codes related to other wheel sensors or ABS issues, indicating a larger problem with the ABS system.
