Wheel Speed Sensor Fault - Rear Right
There’s a problem with the rear right wheel speed sensor or its 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 computer can't read how fast the rear right wheel is turning, which can mess with things like the anti-lock brakes (ABS), traction control, and stability control.
What the computer is actually seeing
The ABS module expects to see a voltage signal from the rear right wheel speed sensor fluctuating between 0V (at rest) and around 5V (moving).
What a healthy reading looks like
The sensor should output between 0.5V to 5V based on wheel speed, with a typical reading around 2V when the vehicle is moving at a low 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.
- 1Check the wiring and connector at the rear right wheel speed sensor for any visible damage or corrosion. Repair as necessary. Decision: If damaged, repair it and retest. If not, proceed to step 2.
- 2Measure the voltage at the wheel speed sensor connector with the vehicle off (should be battery voltage) and again with the vehicle running (should fluctuate based on wheel speed). Decision: If off-spec, replace the wheel speed sensor and retest. If normal, proceed to step 3.
- 3Inspect the ABS module for faults. Check connections and signals from the module to the sensor. Decision: If a fault is present in the ABS module, consider replacing it.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connector to the sensor
- Corroded or poor ground connection
- ABS module failure
Typical repair cost
$$ - $$$

Frequently asked questions
Is it safe to drive with this code?
You can drive, but you're at risk of losing ABS and traction control, which can be dangerous in slippery conditions.
Will this code come back after clearing?
It may come back if the underlying issue isn't resolved, such as a bad sensor or wiring problem.
Why does this code appear with other wheel sensor codes?
It’s common for multiple wheel speed sensor faults to occur together due to shared wiring or an issue in the ABS module.
