Hello and Welcome! I'm Billy and I will assist you with your inquiry. I understand that having car problems can be frustrating so please feel free to ask if any further info is needed.
If you get prompted for a Premium service or a phone call, please ignore that, cause I don't think it is needed at this point.
My apologies for the delay, thank you for your patience.
May I know with whom I'm speaking now?

Having already replaced the sensor, the other causes might be the tone wheel on which the sensor reads, faulty wiring from the sensor to the ABS control unit or even a faulty control unit.

To diagnose this properly, we need to connect diagnostic equipment in order to read the fault codes in the ABS module.

Having the codes, I will be able to explain their meaning, what to check and how to check, in order to confirm the fault and replace/fix as needed.
