On your 1988 Celebrity code 12 means the computer is working properly. You should always get a code 12 whenever you check for codes.
Code 43 has to do with the Electronic Spark Control, specifically the knock sensor. It doesn't necessarily mean the knock sensor has failed, it could be in the wiring
To check the knock sensor measure it resistance. It should read between 3300 and 4500 ohms. If it does not it may mean the knock sensor has failed.
One of our cars recently posted a code 43. When we checked it out it turned out the terminal had come off of the knock sensor. When it was put back on it cleared up the problem.
