Looking at that chart I'm thinking the coolant temp sensor could throw the code 23 since it says coolant/manifold air temp, but I really don't know.
I don't have a volt meter, so I ended up taking it to a dealer (first time EVER I took a car in for someone else to find the problem). The mechanic told me the resistance is way too high, but didn't tell me what the volts were.
I guess I'll try to replace the coolant temp sensor (it has gone bad before).
Thanks for the help!
