Wheel Speed Sensor Circuit Malfunction
There is a problem with the wheel speed sensor 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)
This code means the computer isn't getting a correct reading from the wheel speed sensor, which helps control ABS and traction systems.
What the computer is actually seeing
The ABS control module expects to see a voltage signal that varies based on wheel speed (usually 0-5 volts). If it sees no signal or a continuous voltage, it knows there’s a problem.
What a healthy reading looks like
Normal wheel speed sensor output is 0-5 volts AC or DC, depending on the design, when the wheel spins. Signals should change with wheel 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 at the wheel speed sensor for damage or corrosion.
- 22. Check the resistance of the wheel speed sensor using a multimeter; typical resistance is around 1-2 kΩ.
- 33. Measure the voltage output from the sensor while spinning the wheel; should fluctuate between 0-5 volts.
- 44. If output is stable, inspect the ABS control module for faults; check for stored codes.
- 55. Clear the codes and test drive to see if the code reappears. If it does, consider replacing the sensor.
Common causes
- Damaged wheel speed sensor
- Faulty wiring or connectors
- Corroded terminals
- Faulty ABS control module
Typical repair cost
$100-$300
