Wheel Speed Sensor Circuit Range/Performance Problem (Left Front)
There's a problem with the left front wheel speed sensor signal.
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 left front wheel speed sensor is sending a bad signal to the computer, which can affect the ABS and traction control systems. This sensor normally outputs a voltage signal that varies as the wheel turns, typically around 0.5V to 3.5V depending on wheel speed.
What the computer is actually seeing
The computer expects a smooth, consistent voltage signal from the wheel speed sensor as the vehicle accelerates and decelerates. If the signal jumps erratically or falls outside of normal range, the code triggers.
What a healthy reading looks like
Expected voltage from the wheel speed sensor should vary from 0.5V to 3.5V, depending on vehicle 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.
- 1Inspect the wiring and connectors at the left front wheel speed sensor for damage or corrosion. Check voltage at the sensor while spinning the wheel. If wiring is intact, move to next step.
- 2Using a multimeter, check the voltage output of the wheel speed sensor with the ignition on but engine off. It should read within 0.5V to 3.5V. If out of range, replace the sensor.
- 3Inspect the tone ring for cracks or missing teeth. If damaged, replace the tone ring and retest.
- 4Clear the code and take the vehicle for a test drive. If the code returns immediately, it indicates a fault in the wiring or connector, or confirms a faulty sensor.
Common causes
- Wiring issues (frayed, shorted, or corroded)
- Faulty wheel speed sensor
- Connector problems (loose or corroded)
- Damaged tone ring
- Other ABS system faults

Frequently asked questions
Can I still drive my vehicle with this code?
Yes, but it may affect ABS and traction control performance.
What happens if I ignore this code?
Ignoring it could lead to decreased safety in wet or slippery conditions as your traction control may not work properly.
Why does this code pair with other codes?
Multiple codes can indicate a common problem in the ABS system or related components, such as wiring or sensors.
