This is the left front wheel speed sensor. The code will come on when its not getting the correct readings. Since we have already replaced the sensor this would leave the wiring at the sensor going to the EBCM. If the wiring is good the EBCM is the only other possible issue here. Did you completely reset the system after replacing the sensor? If so than I would get a volt/ohm meter and put the meter on ac voltage turn the wheel while you have it spliced into the wires going to the sensor. If you get a reading than there is a signal if not than we need to find out if there is a broken wire and if not replace and program a new EBCM.
