Wheel Speed Sensor Rear Right Circuit Open
The rear right wheel speed sensor circuit is open or disconnected.
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 can't read the rear right wheel speed because the sensor isn't connected or the wiring is broken.
What the computer is actually seeing
The wheel speed sensor should send a voltage signal as the wheel turns. If the circuit is open, it shows zero volts or no signal when the vehicle is moving.
What a healthy reading looks like
Expect 0-5 volts DC from the sensor while the wheel turns. A working sensor should produce a voltage signal that changes with the wheel 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 connector for the rear right wheel speed sensor. Look for frays, breaks, or corrosion.
- 22. Unplug the connector and check for voltage with the key on (engine off). You should see battery voltage present.
- 33. If no voltage, trace wiring back to the ABS module; repair any damaged sections found.
- 44. If proper voltage is present, proceed to test the sensor. Use a multimeter to check the resistance of the sensor; it should be around 1,000 to 2,500 ohms.
- 55. If the resistance is outside this range or the sensor is not outputting voltage when the wheel is spun, replace the rear right wheel speed sensor.
- 66. After replacement, clear the codes and take the vehicle for a test drive to verify the code does not return.
Common causes
- Broken or damaged wiring to the rear right sensor.
- Corroded connector at the sensor or module.
- Failed rear right wheel speed sensor.

Frequently asked questions
Is it safe to drive with this code?
You can drive, but be careful; ABS may not work properly, especially in slippery conditions.
Will this problem come back after repair?
If all connections and the sensor are fixed, the problem shouldn't return.
Why does this code pair with other wheel speed codes?
Multiple codes indicate issues with other wheel speed sensors or general ABS system wiring, often related.
