To erase the codes you disconnect your battery.
So you were able to start your car by removing that air duct hose assembly? Was it running normal when you did that? Read somewhere that car would start also by removing the air flow meter’s connection. So does that mean it’s bad?
When my car had it’s problem there was no error codes. I got tired of troubleshooting and finally just changed the AFM with a spare that I got off of eBay. That was the fix.
There is a chemical spray at the auto parts store for cleaning afm/map sensors that you could try. There is a thin wire configured in a triangle shape that can be cleaned. It may or may not help.
You got so many codes and anyone of those could be the problem.

Al, finally got around to working on my Maxima. Cleared out all the errors by disconnecting the battery. Ran the Self-Diagnosis again and it came back with 12, 23 & 41. I tested the Throttle valve Switch for continuity and it failed, so I know that I need to replace my throttle valve switch. Moved on to the Air flow meter. It failed its test, so I replaced it with a used one I purchased on ebay from a working Maxima. Before I put it all back together turned over the car and it started right up as smooth as new. Drove it for about 30 minutes with the air conditioner and not a single problem. As far as error 41 is concerned; I will be testing that sensor tomorrow to see what I come up with. If it fails I will add that to my junk yard (I found a yard that has a 1987 that has great parts) shopping list. Thanks for all the advice and recommendations. This place is a real treasure chest of information.
