I know its really confusing isn't it? Shocked there are so many similar sensors in that car!
Major ones I use are
Ignition timing- think it is spark advance at VE cylinder 1 (there is only one that says "at VE cylinder 1"
A/F-lambda before primary catalyic convertor
IAT-internal ambient temp (says exactly that I believe)
Engine speed is clear
Knock-there are tons to choose from. I pick one just to log whether I am getting knock for more my own info
