I just had my check engine light come on a couple days ago, and yesterday I ran the diagnostic and those were the 2 codes I got. The frist one is the knock sensor and the 2nd one is the evap canister. I'm gonna try and test those pieces today sometime and see if I can tell if they're bad or need replacement. I already looked up how to "fix" those pieces off the forums and printed out testing instructions But if any of you know what might be causing these codes or if theyre related and easily fixable I'd greatly appreciate it.
