I have a 1999 civic ex. The knock sensor got broke while replacing the engine. I put a Y8 back into the car. My question is, would a knock sensor from another engine work and if so which one? I don't have the money to buy a brand new one. I bought one off a guy on another forum, but he sent me the oil sending unit instead and now won't return any of my emails or phone calls. This is my only car and I need to get it back up and running asap. Also, would the FIA control valve work off another engine? I think it's a dealer part cause advance and autozone don't carry it. Any info would be greatly appreciated, thank you.
