Wheel Speed Sensor Range/Performance Problem (X-axle)
The wheel speed sensor is reporting an unacceptable value for the X-axle.
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 measures how fast each wheel turns. If one wheel is turning way slower or faster than it's supposed to, it throws this code.
What the computer is actually seeing
The control module detects that the voltage or frequency from the wheel speed sensor on the X-axle is outside of normal operating parameters, usually indicating a discrepancy with actual wheel speed. For example, if the sensor is outputting below 0.5 volts or above 4.5 volts when the vehicle is moving, that's a red flag.
What a healthy reading looks like
Ideal voltage output from the wheel speed sensor is typically around 2.5 volts when the wheel is stationary and can vary with speed up to 5 volts at maximum rotation.
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 at the wheel speed sensor. Look for any signs of damage or corrosion. If damaged, repair or replace as necessary. DECISION: If wiring is okay, move to step 2.
- 22. Measure the voltage at the wheel speed sensor while the vehicle is moving. Ideally, you should see a voltage between 2.5V and 5V. DECISION: If voltage is outside the expected range, replace the sensor. If voltage is normal, go to step 3.
- 33. Check for TSBs related to your vehicle model that may point to a specific ABS module issue. DECISION: If applicable TSBs exist, follow manufacturer recommendations. If no known issues exist, consider replacing the ABS control module.
Common causes
- Faulty wheel speed sensor
- Wiring issues (shorts or opens)
- Corroded connectors
- Faulty ABS control module
- Incorrect tire size or mismatched tires
Typical repair cost

Frequently asked questions
Is it safe to drive with this code active?
It's moderate severity; you can drive but should address it soon to maintain ABS operation.
Will this issue come back after repairing?
If properly diagnosed and repaired, the issue should not reoccur, unless there's an underlying problem.
Why do wheel speed sensors matter?
They're critical for ABS and traction control systems to function properly.
