I ran through the codes on my ECM and came up with a code 46. I can't find that code anywhere. I checked it 3 times. Anyone have any idea what that is?

I have a 93 ZR-1. Code 46 is not in the red service manuals that I have. It goes from 45 to 51. I'm thinking that since I had a bad key, it set the code 46 in ECM memory. I was able to start the car with a good key and what I am seeing is the stored memory code 46. The code is still there even though the book does not address it.
