Right Rear Wheel Speed Sensor Circuit Fault
Indicates an issue with the right rear 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 right rear wheel speed sensor measures how fast the wheel is turning and sends this data to the vehicle's computer. If it fails or has a wiring problem, the system can’t tell if the wheel is spinning properly, which can affect traction control and ABS functions.
What the computer is actually seeing
The vehicle's control module expects a consistent voltage signal from the right rear wheel speed sensor that usually ranges between 0 and 5 volts, depending on wheel speed. A failure might show up as no signal or a signal that is out of expected range.
What a healthy reading looks like
Normal voltage output from the wheel speed sensor should be between 0.5V to 3.5V during standard operation; a steady 0V indicates a circuit fault or sensor failure.
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 for the right rear wheel speed sensor. Look for any signs of damage, corrosion, or loose connections. If found, repair as necessary and retest. DECISION: if wiring/connectors are okay, proceed to step 2; if not, fix and recheck code.
- 22. Measure voltage at the right rear wheel speed sensor while the vehicle is in motion. You should see a voltage reading between 0.5V to 3.5V. DECISION: if voltage is within range, the sensor is likely good; if not, replace the right rear wheel speed sensor and retest the system.
- 33. Check the ABS module for any additional codes or faults. If other codes are present, address them accordingly, as they may relate to this issue. DECISION: if no other faults, and after replacing the sensor the code persists, suspect a faulty ABS module.
Common causes
- Damaged wiring or connectors in the wheel speed sensor circuit
- Faulty right rear wheel speed sensor
- Corrosion at the sensor connection
- Faulty ABS module affecting sensor signals

Frequently asked questions
Can I still drive the vehicle with this code?
Yes, but it might affect your traction control and ABS, increasing the risk in slippery conditions.
Will this code come back after I clear it?
It may come back if the underlying issue is not resolved, particularly a faulty sensor or damaged wiring.
Why does this code sometimes pair with another code?
This code can be related to other wheel speed sensors, or issues within the ABS module that handle multiple wheel signals.
