Wheel Speed Sensor (WSS) Range/Performance Problem (Front Left)
Indicates a problem with the front left wheel speed sensor 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 computer is reading an inconsistent signal from the front left wheel speed sensor, which could cause issues with ABS and traction control systems.
What the computer is actually seeing
The control module is monitoring the voltage output from the wheel speed sensor which should be between 0.5V to 5V depending on the vehicle speed. If the signal drops below the expected threshold or becomes erratic, this code will set.
What a healthy reading looks like
Voltage output from the WSS should be stable and proportional to vehicle speed, usually between 0.5V at a stop to 5V at higher 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.
- 1Inspect the wiring and connectors for damage or corrosion at the front left wheel speed sensor. Check for loose connections.
- 2Measure the voltage output at the wheel speed sensor while the vehicle is in motion. Expected is 0.5V to 5V depending on speed. If the output is outside this range, continue to step 3, otherwise repair wiring as needed.
- 3Test the wheel speed sensor resistance with an ohmmeter. Expected resistance is typically between 800 to 1200 ohms. If resistance is out of spec, replace the sensor.
- 4If the sensor checks out, inspect the control module input signal to ensure it is receiving a stable signal. Replace the module if necessary.
Common causes
- Wiring issues (broken, shorted wire) to the sensor
- Faulty front left wheel speed sensor
- Corrosion or poor connections at the sensor or control module
- Physical obstruction on the sensor (dirt or debris)

Frequently asked questions
Is it safe to drive with this code present?
It's drivable but be cautious; you may lose ABS and traction control functionality.
Will this problem come back after fixing?
If repaired properly, it shouldn't return unless there's another underlying issue like a wiring problem.
Why does this code pair with other wheel speed codes?
Multiple codes can indicate multiple sensors reporting similar issues, often due to wiring faults affecting the signal.
