I know it's a bit late on this, being 2 months after the initial post, but I found this on a search, and thought I'd address it anyways, maybe it will help others in the future or if you have not fixed the problem.

P0325 knock sensor bank 1: well, since you have an inline 4 in the 240sx, it's the only bank there is, and thus it's bank 1, you will only have 1 knock sensor. Place the sensor and make sure to clean the ground on it too, follow the wire to where ever it is.

P0440 Evap system, small leak: Check all vacuum lines coming to and from the evap canister and make sure there isn't a rip or any air leaks, replace all bad lines. You may want to pull the solenoid and clean it out as well. Spray some run-of-the-mill carb cleaner in there, let it dry and reinstall.

Goodluck.
