ABS Wheel Speed Sensor - Right Front Input
Indicates a malfunction in the right front ABS 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)
This code means the computer is getting bad or no signal from the right front wheel speed sensor. It can affect how the brakes work in slippery conditions.
What the computer is actually seeing
The ABS module expects a consistent voltage signal from the right front wheel speed sensor that reflects the wheel's speed. If it doesn't see the expected voltage changes (typically between 0.5 to 4.5 volts), it triggers this code.
What a healthy reading looks like
The right front wheel speed sensor should output voltage in the range of 0.5 to 4.5 volts as the vehicle moves. Ideally, it should represent the wheel speed accurately, with varying pulses as wheel speed changes.
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 wiring and connectors at the right front wheel speed sensor for damage or corrosion. Check for continuity: expected resistance should be near 0 ohms.
- 22. Using a multimeter, measure the voltage output from the right front wheel speed sensor while the vehicle is in motion. Expected voltage should be between 0.5 to 4.5 volts. If there’s no voltage, go to step 3.
- 33. Replace the right front wheel speed sensor if there’s no signal or a persistent fault in the output. If the output is correct, inspect the ABS module or related wiring.
Common causes
- Damaged or corroded wiring to the sensor.
- Faulty right front ABS wheel speed sensor.
- Bad ABS module.
- Poor connection at the sensor or module.

Frequently asked questions
Is it safe to drive with this code active?
You can drive, but be cautious, especially in wet or icy conditions. The ABS may not function properly.
Will this code come back after clearing it?
It may come back if the underlying issue isn't fixed, like a faulty sensor or wiring problem.
Why does this code pair with others?
ABS codes often indicate related issues, such as multiple sensor problems or module failures.
