The check engine light will not turn off
I recently installed both knock sensors and harness on my 2004 Silverado
because I was getting a code that indicated that these were defective. But
after replacing them, I still getting the same code. I already rechecked the
wiring all the way to the computer and found everything to be ok. I don't know
what else to do, could it be a timing issue? I did replace the 5.3 with a 6.0 but I
I think the issue was there before I replaced the engine.
A lot of times, the code that pops up indicating which sensor is detecting the problem is not the issue. You need to do further diagnostic work. So what are the 4 digit code or codes you have now?
Thanks Tom.... I have attached a photo with the codes that I am getting. I do plan on running some more test to the best of my unprofessional experience. I have also checked all of the grounding points that I have found. Hopefully you have some more tips, if not I will have to take it in to the dealership and suffer the expense. Thanks Tom
