Well, the 4-8 code indicates a problem with the left rear wheel sensor circuit. If the sensor was replaced, and no help. Then it can be the wiring, a problem with the pulser, modulator, or the ABS controller itself. You are just going to have to get a mechanic to track down the problem and correct it.
I would start by checking the entire wiring harness for any kind of chaffing, or wear. Even pull and tug a little to see if you can find if there is a problem. I would check the connectors and make sure the signals are properly being transfered.
It could be the controller, but that is a very expensive "lets try this" attempt.
Good luck on fixing this. And let us know what did it.
