hello there every one. Im a first time user on P.O and i wanna know if there is a way to check and see if my ABS wheel sensor is the cause to my light going off. How might i go and check it. I already pulled the code and it read 4-8 meaning what i believe is rear LH wheel sensor. I pulled it off now how do i check to see if that is the culprit? I dont wana spend 125 bucks on a sensor if i dont need to ya know. i did do some research and found a thread about shaving some rust off to make it work. any help would be great.
