ABS Wheel Speed Sensor Fault - Rear Right
Indicates a fault detected with the rear right wheel speed sensor.
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 isn’t getting the right speed info from the rear right wheel, which may affect braking and traction control.
What the computer is actually seeing
The ABS control module sees discrepancies in the wheel speed readings, indicating the rear right sensor is malfunctioning or providing inconsistent signals.
What a healthy reading looks like
Wheel speed should be similar across all four wheels; typically around 0-60 mph during active driving.
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 wiring and connectors to the rear right wheel speed sensor for damage or loose connections. If found, repair/replace as necessary. Decision: If repaired, retest; if no damage, proceed to step 2.
- 22. Check the brake fluid level. Ensure it's at the correct level. Decision: If low, refill and retest; if okay, proceed to step 3.
- 33. Test the resistance of the rear right wheel speed sensor. Expected resistance is typically 1,000-2,000 ohms. If out of range, replace the sensor. Decision: If in range, proceed to step 4.
- 44. Inspect the tone ring for dirt or damage. Clean or replace if necessary. Decision: After cleaning/replacing, retest system for fault code.
Common causes
- Faulty rear right wheel speed sensor
- Damaged wiring or connectors to the sensor
- Brake fluid level low affecting sensor performance
- Corrosion or dirt on the sensor or tone ring

Frequently asked questions
Is it safe to drive with this code?
It’s moderate severity; you can drive cautiously, but expect reduced braking effectiveness until fixed.
Will this code come back after clearing?
If the underlying issue isn’t resolved, yes, the code is likely to return.
Why does this code show up when other wheel codes are present?
The ABS system monitors each wheel independently; issues can often affect multiple sensors simultaneously.
