Wheel Speed Sensor Range/Performance Problem
The wheel speed sensor is reporting a fault in its performance.
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 is not giving the right signal about how fast the wheel is turning, which can mess with the ABS and traction control systems.
What the computer is actually seeing
The ABS control module expects a consistent voltage signal from the wheel speed sensor, typically around 0 to 5 volts. If the signal varies outside expected thresholds or stops, it registers a fault.
What a healthy reading looks like
Wheel speed should produce a voltage signal proportional to the wheel's RPM, typically 0.5V at low speeds to 4.5V at high 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.
- 1Check wiring and connector to the wheel speed sensor for damage or corrosion.
- 2Inspect the sensor mounting and ensure it is firmly attached and not filled with debris or rust.
- 3Measure the resistance of the wheel speed sensor; should be within 1k to 2k ohms. If out of range, replace the sensor.
- 4With the vehicle in motion, use a scan tool to monitor live data from the wheel speed sensor. Look for consistent voltage changes as the wheel turns. If readings are erratic or absent, replace the sensor.
Common causes
- Damaged or corroded wiring to the wheel speed sensor
- Faulty wheel speed sensor
- Poor connection at the sensor or control module
- Brake system malfunctions affecting sensor operation
