How to tell which wheel speed sensor is bad?

Code readers often flag a sensor error without specifying which wheel is failing, leaving owners to check the wiring or resort to replacing parts one at a time. This lack of location data leaves dashboard lights on and disables AWD until the exact faulty sensor is found.

What people tried

Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.

  1. 1
    Replacing sensors one at a time until the code disappears
  2. 2
    Checking live data to see which wheel speed sensor is dropping out
  3. 3
    Probing sensor connectors with a multimeter
  4. 4
    Replacing individual sensors without checking the tone ring or bearing

“Recently bought a 16 AWD Rogue S and the tpms and the abs sensor on the passenger front is not responding. So I have no awd and every light is on.”source ↗
