Wheel Speed Sensor Circuit Range/Performance Problem
This code indicates an issue with the wheel speed sensor reading or its circuit.
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 monitors how fast each wheel is turning. If it reads incorrectly or not at all, it can cause issues like ineffective ABS or traction control.
What the computer is actually seeing
The ABS control module expects the wheel speed to change in a specific range based on vehicle speed and throttle position. If it detects a reading too high or too low, it triggers this code.
What a healthy reading looks like
Typically, wheel speed sensors should output a voltage between 0-5 volts, with a frequency that varies based on wheel rotation rates, usually around 1-2 Hz at low speed and increases proportionally with 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 connectors of the wheel speed sensor for damage, wear, or corrosion. If damage is found, repair or replace as necessary. Decision point: Is there visible damage?
- 22. Use a multimeter to check the voltage output of the wheel speed sensor while the vehicle is moving. Expected voltage should be between 0-5 volts. Decision point: Are voltage readings within range?
- 33. Check the ABS module for any related trouble codes using a scan tool. If other codes are present, diagnose them first. Decision point: Are there additional codes?
- 44. Test the wheel speed sensor with a scope to observe the wave pattern. An inconsistent or flat line could indicate a sensor fault. Decision point: Is the sensor output consistent?
- 55. If all checks pass, consider inspecting the ABS control module for faults.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connectors to the sensor
- Corrosion or dirt in sensor connectors
- Faulty ABS control module
- Inconsistent sensor output due to wheel bearing play

Frequently asked questions
Is it safe to drive with this code?
It's not ideal, as it can affect braking and traction control systems, but the vehicle is still generally drivable.
Will this issue return after fixing?
If the root cause is correctly identified and addressed, it should not return.
Why does this code appear with other ABS codes?
ABS and traction control systems rely on accurate wheel speed readings, so multiple related codes can indicate a broader sensor or control module issue.
