The knock sensor is an odd ball thing. If it is on a stock ecu, you will throw a CEL, but not always. It depends on the rpm range, and the throttle position. It only checks for knock in certain situations. Most likely the engine is in good running shape, and will not need to correct for knock. If it does kick the CEL, it will put it in limp mode of sorts, basically just going to the richest fuel table on the BIN. The knock sensor is used on most of the cars requiring premium fuel as a stupidity prevention device. So, yes, you should be just fine driving it home. If it has a loud knock from startup, it most likely has other issues that having a knock sensor hooked up won't resolve anyway.
