Wheel Speed Sensor Right Front Circuit Range/Performance Problem
The right front wheel speed sensor circuit is experiencing a range or performance issue.
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 is getting signals from the right front wheel sensor that don't match what it expects. This is like if your speedometer suddenly shows zero while you’re moving.
What the computer is actually seeing
The ECU expects a steady voltage output from the right front wheel speed sensor that corresponds to wheel speed; typically around 0.5V at a stop and increases with speed, reaching up to 5V at full speed. An abnormal signal or out-of-range voltage prompts this code.
What a healthy reading looks like
Voltage should range from 0.5V (stopped) to about 5V (near full speed). Resistance should be between 1,000 to 2,500 ohms when measuring the sensor directly.
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 front wheel speed sensor for corrosion or damage. If found, repair and retest. Decision: Is the wiring intact?
- 22. Measure the voltage at the sensor connector with the ignition on and the wheel stationary. Expect near 5V. Decision: Is the voltage present and correct?
- 33. If voltage is not correct, check for continuity in the wiring back to the ECU. Decision: Is the wire intact?
- 44. If wiring checks out, replace the right front wheel speed sensor and retest. Decision: Did the code clear and performance improve?
Common causes
- Damaged wheel speed sensor
- Corroded connections at the sensor or ECU
- Wiring issues such as shorts or open circuits
- Malfunctioning ABS module
- Moisture or dirt ingress into the sensor housing

Frequently asked questions
Is it safe to drive with this code present?
You can drive, but pay attention to your speed and braking performance. If the ABS engages unexpectedly, have it checked soon.
Will this code come back after repair?
If the repair is done properly, it should not come back. Ensure all connections are clean and secure.
Why might it pair with other codes?
This code can be triggered alongside other wheel speed sensor faults or ABS issues because they share the same system.
