=== there is no knock sensor in any car and whoever told you that one exists is not being truthful with you ... if you are having a knocking problem in the engine then it is time to trade or rebuild the motor ... go to the local auto supply and get one of those counter dudes to listen to your car and tell you what's wrong == those guys are very helpful and it is free ... if you are advised to use some motor ""honey"" like STP product that is only a band-aid on a deep gash ... but it will get you to the trade or the re-builder ...........
