My CEL just came on and I went to Advanced Auto Parts to get the code so I could ask for help but when I got there the only code that came up is from my abs sensor (which I already knew was malfunctioning). Is there any way that that sensor can make the check engine light come on even after all this time?

 

As long as the part is still failing it will keep causing the CEL to kick on. Clearing a code doesn't stop it ffrom coming back on.
