Does the CEL come on at a certain level of knock? If so, at what level?
 
isnt there a light for the actual knock sensor if it isnt working properly? like if it gets wet or something?

mine came on on my 91 after a heaterhose busted, but went away after everything dried off.
 
wet shouldnt effect it... unless its really old and damaged and the inner electroics are exposed. The only time a the cel will come on for the knock sensor is if its damaged or not getting a proper signal... not for any amount of knock.
