Wheel Speed Sensor Circuit Inc. or High
This code indicates a problem with the wheel speed sensor circuit reading too high or intermittent.
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 computer is getting a signal from the wheel speed sensor that doesn't make sense, usually showing a value that's higher than expected, which might mean there's a wiring issue or the sensor is faulty.
What the computer is actually seeing
The ABS module expects wheel speed signals in volts that correspond to actual wheel speeds, typically ranging from 0 to 5 volts. If it sees a constant high signal or a brief spike above expected values, it triggers this code.
What a healthy reading looks like
Wheel speed should vary with vehicle speed, generally between 0-5 volts; at 10 mph you might see around 1-2 volts, at 30 mph it should increase closer to 4 volts.
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. Look for physical damage, corrosion, or loose connections. If you find issues, repair or replace as necessary. Decision Point: Does connector/wiring look good?
- 22. Use a multimeter to check the sensor output. Measure the voltage at the wheel speed sensor while spinning the wheel. It should fluctuate as expected. Decision Point: Is the voltage output normal (0-5 volts)?
- 33. If the sensor output is abnormal, replace the wheel speed sensor. Recheck the circuit. Decision Point: Does the code return?
- 44. If the code returns, check the ABS control module and for any potential fault in the circuit between the sensor and the module.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connectors
- Corroded terminals
- Issues with the ABS control module
- Wheel bearing problems affecting sensor placement

Frequently asked questions
Is it safe to drive with this code?
While it may be drivable, the ABS system may not function correctly, which can affect braking. Fix it soon.
Will this code come back after I clear it?
If the issue isn't resolved, such as a bad sensor or wiring, it will likely return.
Why does this code pair with other codes?
Faulty wheel speed sensors can affect multiple wheels and the various control modules, leading to multiple codes showing up.
