Wheel Speed Sensor Signal - Rear Right
The rear right wheel speed sensor is not sending a valid signal to the control module.
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 rear right wheel speed sensor is either damaged, disconnected, or failing to send the correct speed information to the computer. This affects traction control and ABS functions.
What the computer is actually seeing
The ABS control module monitors the voltage signal from the rear right wheel speed sensor. When the sensor is working, it sends a signal between 0.5 to 5 volts depending on wheel speed. If the signal is not received or falls out of range, the code sets.
What a healthy reading looks like
Expected voltage from the sensor while driving should be between 0.5V (stationary) and around 5V (at 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 condition of the wiring and connectors leading to the rear right wheel speed sensor. Look for signs of wear or damage. If any issues are found, repair these before proceeding.
- 2Test the voltage at the sensor connector while the vehicle is in motion. You should see a varying voltage between 0.5V and 5V. If no signal is present, proceed to step 3.
- 3Disconnect the sensor and measure the resistance. It should typically be around 1,000 to 2,000 ohms. If resistance is out of range, replace the sensor.
- 4If the sensor is good, check for continuity in the wiring harness to the ABS control module. Repair any breaks or shorts found.
- 5If wiring is intact and sensor is operational, test the ABS module. If communication is lost with multiple sensors or outputs, the module may need replacement.
Common causes
- Damaged wheel speed sensor
- Loose or corroded electrical connections
- Damaged wiring harness
- Faulty ABS module

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity; you can drive but expect potential issues with ABS and traction control. Fix it soon.
Will this code come back after I clear it?
If the underlying issue isn't fixed, the code will likely return.
Why does this code appear with others?
Codes often trigger due to issues in related systems; a problem in one wheel speed sensor can affect others.
