Wheel Speed Sensor Circuit Problem (Right Rear)
There's an issue with the right rear wheel speed sensor signal.
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 is either not sending a signal or the signal is too weak. This can cause issues with traction control and antilock brakes.
What the computer is actually seeing
The ABS control module monitors the voltage signal from the right rear wheel speed sensor. A voltage lower than 0.5 volts or inconsistent signals during vehicle movement can trigger this code.
What a healthy reading looks like
Expected voltage signals should be between 0.5 to 12 volts, depending on vehicle 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. Inspect the wiring and connectors for the right rear wheel speed sensor. Look for damage, corrosion, or loose connections. Repair as necessary. Decision: Is wiring intact? If yes, proceed to step 2; if no, repair and retest.
- 22. Measure the voltage at the right rear wheel speed sensor connector with the ignition on (engine off). You should see around 5 volts. Decision: Is voltage present? If yes, proceed to step 3; if no, check for open circuits or issues in the wiring harness.
- 33. Check the resistance of the right rear wheel speed sensor. It should typically be around 1,000 to 2,000 ohms. Decision: Is resistance within spec? If yes, proceed to step 4; if no, replace the wheel speed sensor.
- 44. Clear the code and take the vehicle for a test drive to see if the code returns. Decision: Does code reappear? If yes, consider replacing the ABS control module; if no, problem is resolved.
Common causes
- Damaged right rear wheel speed sensor
- Corroded or damaged wiring/connectors
- Faulty ABS control module

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity, which means you can drive, but you should fix it soon to ensure proper functionality of ABS and traction control.
Will this code come back after clearing it?
If the underlying issue is not addressed, yes, the code will likely return.
Why does this code sometimes pair with other codes?
When there are issues with the wheel speed sensor, it can affect other modules like ABS or traction control, leading to multiple fault codes.
