I have a 94 civic with a 98 JDM Type-R engine in it. I kept getting a code 23 which is a knock sensor code. I just changed the knock sensor and I'm sure everything is plugged in and correctly wired. Someone mentioned to me that in Japan they use higher octane fuel than in the USA, which I'm thinking is throwing a knock code. I am using 91 octane right now. Has anybody else had this problem with a J-spec engine? Any tips please reply. Thanks.
