Knock and ABS questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I had posted a question before with these question, took the advice given, but am still encountering issues. So I figure I would try again.

First the knocking. The CEL is off, but after the truck warms up, I will encounter knock and the CEL comes on with a 43. I rep;aced the knock sensor, ESC, and ignition module. So now over $200 later I am still having the problem. Any ideas?

Now the ABS. I am getting an ABS code of 6, which is speed sensor. I replace the speed sensor, and I am still getting the same code. I pulled the battery for 30 minutes to clear everything, but it came right back on as soon as I turned the key. So now I have almost $100 in fixing this issue with no progress.

I am getting frustrated!! Some one please help!!

Thanks

Jim

I would check the wiring to both systems, and your grounds. Sounds like a wiring issue to me.
