Code says Lft front Wheel Sensor is Malfunctioning

the sensor is in the hub assembly, and you will need to replace it to fix the problem. at my shop its around $200 parts and labor it can be easy with the right tools but things don't always work how they are supposed to. also check to see if the wires are all intake they sometimes have a habit of being destroyed.

the wheel bearing has to be replaced nondealer can do lt

You cannot just change the sensor. Need to replace the whole bearing assembly that has the sensor included. Front assembly runs $250 and labor probably another $250. Rears are $100 and $200 labor on 2000 LeSabre. Just had some problem. EWilson Michigan
