Wheel Speed Sensor Range/Performance Problem (Left Front)
Issue 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 isn't sending the right information to the computer, which may cause issues with traction control or ABS.
What the computer is actually seeing
The computer expects a consistent voltage signal that changes as the wheel spins; if it sees a steady voltage or erratic readings, it flags the issue.
What a healthy reading looks like
The sensor should output between 0.5V to 5V, with a frequency of 1-60Hz depending on 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.
- 1Inspect the left front wheel speed sensor and wiring for any visible damage or corrosion. Decision: Is there visible damage? If yes, repair or replace the sensor/wiring.
- 2Check the voltage output of the left front wheel speed sensor with a multimeter. Expected output should be between 0.5V to 5V. Decision: Is the output within range? If no, replace the sensor.
- 3Inspect the connector for the left front wheel speed sensor for any loose connections or corrosion. Decision: Is the connector secure and clean? If no, repair the connector.
Common causes
- Damaged wheel speed sensor
- Corroded connector pins
- Wiring harness issues
- Faulty ABS control module
