Hey All, I've been getting a knock sensor ECU code (code 22 with FreeSSM) lately and have all the symptoms associated with a faulty knock sensor. I am trying to find a suitable replacement whether it be factory or not. My issue though, is for some reason my specific model Impreza almost never shows up anywhere, whether it's finding parts that fit or searching for my model on subaru's official site and other places. I was hoping to get some help figuring out why this model is so illusive and ways to get around this, for example finding another model with the same parts that I can use for reference instead? It's a 2002 Impreza RV 2.0L SOHC AWD 5 speed manual Hatchback, with an EJ20 engine. I have asked a few sellers of Knock Sensors suited for EJ20 whether it fits my model but they say it doesnt and can't find a suitable product so i'm pulling out my hair. The garage wants at least $250 for the job (if they can find the right part), but I've seen that you can buy factory ones for ~$80, knock-off's for ~$30 and replace it yourself so I'm trying to go the cheaper route. Any help would be awesome!! Cheers, Tom
