Wheel Speed Sensor Out of Range (Left Rear)
The left rear wheel speed sensor is reading outside normal parameters.
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 gets data from the left rear wheel speed sensor, and if it sees values that don't match what it expects, it throws a code. This could mean the sensor is faulty or there’s a wiring issue.
What the computer is actually seeing
The computer looks for a voltage signal from the wheel speed sensor, typically between 0.5 to 3.5 volts DC. If the signal falls outside of this range, it sets the code.
What a healthy reading looks like
Expected wheel speed is typically around 0-30 mph during normal driving conditions. A malfunction occurs if readings are inconsistent during movement.
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 to the left rear wheel speed sensor for any visible damage or corrosion. Decision: If damaged, repair and retest. If okay, proceed.
- 22. Use a multimeter to check the voltage signal at the wheel speed sensor while the vehicle is in motion. Expected voltage should fluctuate between 0.5 to 3.5 volts DC. Decision: If voltage is out of range, replace the wheel speed sensor. If within range, proceed.
- 33. Check the ABS module for any fault codes or updates, as issues there can affect sensor readings. Decision: If other faults exist, address them first. If no issues are present, consider replacing the ABS module.
Common causes
- Faulty left rear wheel speed sensor
- Damaged wiring or connectors
- Issue with the vehicle's ABS module

Will the code come back after clearing it?
If the underlying fault isn't fixed, the code will likely return.
Why does this code appear with others?
Wheel speed sensor faults often relate to ABS problems or can indicate issues with braking system components.
