Wheel Speed Sensor (WSS) - Front Right
Fault in the front right 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 front right wheel speed sensor is not sending the right signals, which is important for the ABS and traction control systems to work properly.
What the computer is actually seeing
The ABS control module monitors the wheel speed sensor input and expects to see a signal that fluctuates in voltage as the wheel spins (typically between 0.5V and 5V) depending on the speed of the vehicle.
What a healthy reading looks like
Sensor signal should fluctuate between 0.5V and 5V while the vehicle is moving; if stationary, signal should be close to 0V until movement.
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.
- 1Check the battery voltage at the sensor connector (should be around 12V).
- 2Inspect the wiring and connectors for damage or corrosion; repair if necessary.
- 3Measure the resistance of the wheel speed sensor (should be between 1,000 and 2,500 ohms).
- 4If resistance is out of spec, replace the sensor; if it’s good, check signal voltage at the ABS module.
- 5If signal is good, there may be an ABS module issue; consider testing/replacing module.
Common causes
- Damaged wheel speed sensor
- Corroded connector at the sensor
- Broken wiring harness
- Wheel bearing issues
- Faulty ABS module

Frequently asked questions
Is it safe to drive with this code?
It's not recommended; the vehicle's ABS and traction control may not function properly.
Will this problem come back after clearing the code?
If the cause is not fixed, the code will likely return.
Can this code affect performance in bad weather?
Yes, lack of proper wheel speed inputs can impact stability and traction in slippery conditions.
