Wheel Speed Sensor Circuit Failure (Right Front)
Indicates a fault in the right front wheel speed sensor circuit.
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 system is not getting a correct signal from the right front wheel speed sensor, which measures how fast the wheel is turning. This can cause the ABS or traction control system not to work properly.
What the computer is actually seeing
The ABS control module monitors the voltage signal from the right front wheel speed sensor, which should vary as the wheel spins. If this voltage signal stays too low (under 0.5V) or is completely absent, it triggers the code.
What a healthy reading looks like
Typically, the wheel speed sensor outputs a voltage between 0.5 to 5V, depending on the wheel speed. At a stop, it should be around 0V, while it increases with speed.
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. Check the right front wheel speed sensor connector for damage or corrosion, and ensure it's securely connected. DECISION: If damaged, repair or replace the connector; retest. If fine, proceed to step 2.
- 22. Inspect the wiring from the connector to the ABS module for any visible damage or wear. Use a multimeter to check for continuity. DECISION: If there's a break in the wire, repair it; if the wiring is good, move to step 3.
- 33. Test the voltage output of the right front wheel speed sensor while spinning the wheel (supports vehicle speed sensor checks). Expect a voltage between 0.5V and 5V as the speed increases. DECISION: If readings are out of expected range, replace the wheel speed sensor; if readings are normal, check the ABS control module.
Common causes
- Damaged wheel speed sensor
- Corroded or damaged wiring harness
- Loose connector at the wheel speed sensor
- Faulty ABS control module

Frequently asked questions
Is it safe to drive with this code?
It's generally safe to drive, but you should fix it soon since it impacts ABS and traction control performance.
Will the code come back after clearing it?
If the underlying issue isn't resolved, the code will likely return.
Why does it seem related to other sensors?
Because the ABS system relies on multiple wheel speed sensors, a fault in one can trigger issues with system performance as a whole.
