Wheel Speed Sensor Right Front Circuit
Issues with the right front 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 front wheel speed sensor is not giving accurate speed data, which can affect braking systems and traction control.
What the computer is actually seeing
The ABS control module sees that the signal from the right front wheel speed sensor is out of range or missing.
What a healthy reading looks like
When functioning, the wheel speed should read between 0 and 255 km/h, typically 15-20 km/h while 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 the wiring and connector at the right front wheel speed sensor. Look for fraying, corrosion, or disconnection. Repair as necessary and retest.
- 22. Check the sensor itself for damage or contamination. Clean or replace the sensor if needed and retest the circuit.
- 33. Measure the resistance of the right front wheel speed sensor. Expected resistance is usually between 1,000 to 2,000 ohms. If outside this range, replace the sensor.
- 44. Use a scan tool to monitor sensor output while the wheel is turning. The output should change according to wheel speed.
- 55. If all else checks out, inspect the ABS control module for faults and connections.
Common causes
- Damaged wheel speed sensor
- Faulty wiring/connector issues
- Wheel bearing problems
- Corroded terminals at the sensor
- Malfunctioning ABS control module

Frequently asked questions
Is it safe to drive with this code active?
It may be drivable, but you'll likely experience issues with traction control and antilock brakes.
Will this issue come back after repairs?
If repaired correctly, it shouldn't return unless there are other underlying issues.
Why does this code appear with others?
Wheel speed sensors are often part of an interconnected system, so multiple codes can trigger if one sensor fails.
