Code 43, how bad is it?
I already know that code 43 is the knock sensor trouble code. What would be the worst case scenario if there is no short in the circuit or a bad knock sensor, and how much time and money would be spent repairing it. Don't sugar-coat the news no matter how bad it is. All help and info is greatly appreciated.

I am really starting to hate electronics. (Even more than before)

Some ECMs/masks force knock in order to test the system. If the knock does NOT occur, then code 43 pops up. Just going to 92 octane on a car that normally uses 87, or even a colder thermostat can prevent the knock from occurring.
