Wheel Speed Sensor Circuit Range/Performance Problem (Left Front)
Indicates a problem with 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 left front wheel speed sensor isn't signaling correctly, which affects traction control and ABS performance.
What the computer is actually seeing
The PCM expects a voltage signal from the wheel speed sensor that fluctuates between 0.5V to 5V based on wheel rotation speed. If the signal is unstable or out of this range, a fault is detected.
What a healthy reading looks like
Voltage signal from the sensor should vary between 0.5V and 5V while the vehicle is moving.
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 connector for the left front wheel speed sensor. Look for frays, corrosion, or damage.
- 22. Check the sensor itself for any debris or contamination that may be affecting its performance.
- 33. Use a multimeter to test the voltage signal from the sensor while the wheel is being rotated. Confirm it fluctuates between 0.5V and 5V.
- 44. If the signal is out of range, replace the wheel speed sensor and retest.
- 55. If the signal is in range, check the ABS module and its ground.
- 66. Consider scanning for other codes that may indicate additional issues with the ABS system.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connector
- Contamination or debris on the sensor
- Corroded terminals
- Failed ABS module

Frequently asked questions
Is it safe to drive the vehicle with this code?
It's moderately unsafe; traction control and ABS may not function, increasing the risk of wheel lockup.
Will this code come back after clearing it?
If the underlying issue isn't fixed, the code will likely reappear.
Why does this code appear with another wheel sensor code?
It can indicate an overall ABS system issue, affecting multiple sensors.
