The abs light continues to come on and that turns off the traction control. Then when I use the brakes they say I need a left front wheel sensor can you help?

Hi,

The wheel speed sensor on the front of this vehicle is integral with the front hub assembly. When the sensor fails, the hub needs to be replaced. This video shows the job being done on a similar car but the process is the same.

Here are the directions specific to your vehicle. The attached pics below correlate with the directions.

Tighten the NEW wheel bearing/hub bolts to 130 Nm (96 lb ft).
