Go into measuring blocks and log wheel speed of all 4 wheels. It should confirm whether the sensor is giving a reading or not.

Then, if you're handy with a spanner, swap the faulty sensor with the opposite side (if they aren't sided) (I.E. faulty osr sensor swapped with good nsr sensor). Clear codes and road test/log wheel speed again. See if fault migrates with sensor or whether it has stayed on the same side.

If it migrates = duff sensor; new one required.

If it doesn't then the fault is either abs sensor pickup/wiring/ecu.
