left rear wheel speed sensor

ok i had the car scaned last night and it come up with the speed sensor, what do i have to do to fix it??

the car is a 04 gt

You need to replace the left rear wheel hub with ABS, make sure its abs since it includes wheel sensor. Here is a link replacing 2002 Pontiac Grand Prix Problem Wheel Hub Bearings Drive Train Axles 6 Cyl Front takes about 1 hour to do this.The rear should be the same directions or just Google rear wheel hub replacement.

ok i was thinking that i needed to replace the whole hub, i just wanted someone to tell me the same thing

thanks

Yep just pull out the drivers rear hub and swap it with a new one.
