I have a 02 accord se and I'm having an issue with my knock sensor which is causing serious damage to my car and performance issues so it's not shifting correctly. The part i bought from the store has a bolted end so you can use a socket wrench. But when I went to take it off the part on the car is round and it has two pins instead of one. Can anybody help because the auto part store said multiple times that I got the right part. Not sure how to post a picture of it

2. The knock sensor location is near the oil filter and should look like this. If it looks different, someone likely replaced it before.
