I just joined the site. I have just purchased and 01 CRV. It’s throwing a knock sensor code. I can’t find the knock sensor. I have just figured out ,I think, that this is not the original engine. It’s a 1B18B. The wiring connector is on the harness for the KS but I’m not sure where to go from here to clear this code. It starts and runs smooth but has poor acceleration. Thanks for any information
