Wheel Speed Sensor Circuit Range/Performance Problem (Left Front)
Indicates a problem with the left front wheel speed sensor.
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 giving the computer the correct speed data for that wheel, which can affect stability control and ABS functions.
What the computer is actually seeing
The ABS module expects wheel speed values from the left front sensor that should be within a specific range based on vehicle speed and conditions. Figures usually around 0-60 mph, reflecting sensor output of 0-12 volts depending on wheel speed.
What a healthy reading looks like
Wheel speed sensor output should be between 0.5 to 4.5 volts when the vehicle is stationary; should increase up to 12 volts as vehicle speed increases.
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.
- 1Check wiring and connector condition for left front wheel speed sensor. Look for frays, corrosion, or loose connections. Repair if necessary.
- 2Using a multimeter, test the voltage output of the left front wheel speed sensor with the wheel stationary. Expected voltage should be around 0.5 to 4.5 volts. If outside this range, replace the sensor.
- 3Visually inspect the sensor for physical damage or contamination (dirt, rust). Clean or replace as necessary.
- 4If sensor tests okay, perform a full system scan to check for ABS module issues. Monitor outputs with the scanner while driving to ensure proper function.
Common causes
- Damaged wheel speed sensor wire
- Faulty left front wheel speed sensor
- Corrosion or dirt on the sensor connector
- Failed ABS module

Frequently asked questions
Is it safe to drive with this code present?
It's safe to drive, but you might lose ABS and traction control functions, which can be a safety risk in slippery conditions.
Will this code come back after clearing it?
It might, especially if there's an underlying issue with the sensor or wiring that wasn't fixed.
Why does this code pair with other codes?
It often relates to other issues in the ABS system or wheel speed sensors on other wheels.
