Hallo and thanks for your question in the autoaid Community.
Your described fault Code means: 5707 ECU internal error and the Code 5112 means the Right Front speed Sensor is faulty. Now the question ist, which Type of Sensor has you removed? Front or back?? If you have the Front Right Sensor renewed, then you should measure the wirings from the Sensor to the ABS Ecu. If there is älteste okay, then you CAN Look in the is values, there should every Sensor displayed and now turn the wheel with your hands. The you should See a Signal or speeding display. To Check If this ist correct, you can Test this Same procedure at the left side.
Sometimes the Speed Transmitter under this ABS Sensor is rotted or faulty and makes this Problem.
The other Code means an internal ecu error and this means that you have to replace this ecu.
