Wheel Speed Sensor 3 Circuit Range/Performance Problem

The wheel speed sensor measures how fast a wheel is turning. If it detects an out-of-range speed for one of the wheels (like wheel 3), it triggers a fault code.

The ABS module expects voltage readings from the wheel speed sensors in a specific range (typically 0 to 5 volts). If the sensor on wheel 3 gives a reading outside this range, or if there’s no reading at all, the code will be set.

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.

1. 11. Inspect the wiring and connectors at the wheel speed sensor 3 for any visible damage or corrosion. Repair as necessary. Decision: If wiring is intact, proceed to next step.
2. 22. Check the voltage at the wheel speed sensor connector using a multimeter. You should see voltage readings between 0.5 to 5 volts while the vehicle is moving. Decision: If voltage is within range, replace the sensor. If not, check the wiring further down the harness.
3. 33. Inspect the tone ring for damage or debris. Ensure it is aligned properly with the sensor. Decision: If the tone ring is damaged, replace it and test the sensor again.

• Open circuit in the wiring harness
• Corroded or damaged connector at the wheel speed sensor
• Faulty wheel speed sensor 3
• Speed sensor tone ring damage or misalignment
