My ABS light is on and I went to the local O'reillys auto parts store so they could check it out for me. They found 3 codes, C1230 C1237 and believe the 3rd one was C1300, it was something about the ABS pump. I startred by clea tninge rear wheel sensor. That did not help so I replaced it. That did not do anything either. I hate to start throwing more parts at it, but I guess I can do that, or go to my local dealer and get robbed. Anyone have any suggestions where I should go from here?

 

Would help if you told us what year truck you have. Trim level might also be nice to know, I checked your profile and it's blank.

 

sorry about that, guess that would help!! its an 08 f150 xlt with the 5.4.
