Wheel Speed Sensor Right Rear Circuit
A problem has been detected in the right rear 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 right rear wheel speed sensor is either malfunctioning or the circuit is open/shorted, affecting traction control and ABS.
What the computer is actually seeing
The ABS or traction control module monitors the voltage from the right rear wheel speed sensor, typically expecting a variable voltage signal ranging from 0 to 5 volts as the wheel rotates. If the sensor returns a constant voltage (e.g., 0V or 5V) or falls outside expected thresholds, it raises the fault code.
What a healthy reading looks like
0-5V signal from the wheel speed sensor that varies with wheel speed; should match left rear wheel speed to maintain proper ABS function.
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 at the right rear wheel speed sensor for damage or corrosion. Repair as necessary. Decision: If wiring is damaged, repair it and retest the system.
- 22. Check the resistance of the wheel speed sensor (should be around 1-2 kΩ). If it’s outside of this range, replace the sensor. Decision: Replace sensor if faulty.
- 33. Measure the signal voltage at the wheel speed sensor connector while the wheel is rotated (should fluctuate between 0-5V). If no signal or a constant value is present, check for circuit continuity and ground. Decision: If no signal is present, check the ABS module wiring; if the circuit is good, replace the ABS module.
- 44. Clear the fault code and take the vehicle for a test drive. Observe if the fault code returns. Decision: If the code reappears, further diagnosis of the ABS module is needed.
Common causes
- Faulty wheel speed sensor
- Damaged wiring or connectors in the sensor circuit
- Corroded terminals at the sensor or connector
- Failed ABS module

Frequently asked questions
Is it safe to drive with this code?
Moderate severity means you can drive, but be aware that ABS and traction control may not work properly, especially in adverse conditions.
Will this code come back after being cleared?
If the underlying issue isn’t resolved, the code will likely return after driving.
Why is this paired with other wheel speed sensor codes?
Multiple wheel speed-related codes may trigger when there's a fault affecting the ABS system's ability to read wheel speeds correctly.
