Wheel Speed Sensor Circuit Malfunction (Left Front)
There's a fault in the left front 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)
The computer detects a problem in the wiring or sensor for the left front wheel speed, which can affect traction control and ABS.
What the computer is actually seeing
The computer expects a specific voltage level between 0.5V and 2.5V from the wheel speed sensor, indicating the wheel's speed. If it receives no signal or an out-of-range voltage (above 2.5V or below 0.5V), it triggers the fault code.
What a healthy reading looks like
Voltage from the sensor should vary based on wheel speed, typically between 0.5V and 2.5V during operation.
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 left front wheel speed sensor. Look for frays, corrosion, or loose connections. If found, repair or replace the damaged wiring/connector.
- 22. Test the voltage output of the left front wheel speed sensor with a multimeter. You should see a varying voltage between 0.5V and 2.5V while the wheel is turning. If not, the sensor is likely faulty.
- 33. If the sensor is functioning correctly, check the ABS module for any fault codes or damages. Follow the manufacturer diagnostic steps to pinpoint issues with the ABS module.
Common causes
- Damaged wheel speed sensor
- Faulty wiring or connectors to the sensor
- Corrosion or dirt in the sensor connector
- Faulty ABS module
