I need some information please- I have a 2000 grand am and the other day the check engine light came on and after having the code read we were told it was a knock sensor but were also told our car has 5 of them and we would have to take it to a dealership to find out which one was bad, well the light went off that same day and hasnt been back on, is that good or bad and also do you have to take it in to find out which is bad or is there a way to tell on your own and also how do you find the location of them? Is it something you can change on your own? Thanks for any help
have the same problem?
