Front Wheel Speed Sensor Range/Performance Problem
This code indicates an issue with the front 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 front wheel speed sensor tracks the speed of the wheel. If it's reporting incorrect data, it can cause issues like poor traction control or ABS performance.
What the computer is actually seeing
The computer monitors the voltage signal from the front wheel speed sensor. It expects a consistent signal that correlates with actual wheel rotation speed. If the voltage is inconsistent or out of the expected range, this code sets.
What a healthy reading looks like
The expected sensor voltage should fluctuate between 0.5V to 2.5V while the wheel is turning at normal 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 wheel speed sensor for physical damage or debris.
- 2Check the wiring and connector for corrosion or loose connections.
- 3Measure the voltage at the sensor terminals while spinning the wheel, expect 0.5V to 2.5V.
- 4Compare the front wheel speed sensor value to the rear wheel sensors at various speeds, look for significant discrepancies.
Common causes
- Dirty or damaged wheel speed sensor
- Wiring issues to the sensor
- Faulty ABS control module
- Incorrect sensor gaps

Frequently asked questions
Is it safe to drive with this code active?
It can be driven, but expect decreased performance from the ABS and traction control systems.
Will this problem come back after clearing the code?
If the underlying issue isn't fixed, the code will likely return after driving for a short distance.
Why do I see this code with other sensor codes?
Sensor range issues often pair with other sensor failures, especially if the underlying wiring or module is shared.
