does a knock sensor from a 99 SI fit and work the same for a 98 EX? I know the part numbers are different, but I have heard a few people tell me they work. Just need to know before I buy one for 50 bucks, while my brother has one from his 99 SI motor. For what it's worth, the SI motor was hydrolocked from the previous owner.

 

not 100% sure on this but i believe d-series do not use knock sensors. b-series do

 

no they do use them. i had a code that i pulled up. faulty sensor. plus, it's killing my gas mileage. i'm doing about 20mpg...
