Truck throwing codes
 

My truck is throwing two codes out and don't know what they are. Help!!! The codes are "C0035" & "C0040". :booo:

I believe that C0035 is left front wheel speed circuit malfunction. And C0040 is right front wheel speed circuit malfunction. HTH

Thanks :ok1: Just got my truck back today from the dealer. They checked the brakes & replaced the fuel filter. I think I'll be going back to the dealer so they can check it again.

Did the dealer fix it?

No, :booo:They said it's the wheel speed sensors. It has nothing to due with the work they did on the brakes. I'm going to replace both wheel speed sensor when I due the wheel bearings in a week to see if this well fix it.

WSS comes with the hub bearing assembly, on the plus side. :U:

There have been some guys that pull the sensor and clean it and the reluctor ring. It gets them by for a while.
