no maf , that is correct, the 91 is map based air flow, (+IAT) that uses manifold vacuum to calculate air flows.
yes, we can see all sensors with the scan tool per that link, the FSM shows the same data. same 32 params (or pids)
yes, you can check the sensors 1 by with ohms or or volts.
the TPS output is about 1v at idle, and 4v WOT.
the ECT reads about 300 ohms hot, (hot engine, unplug it measure sensor ohms) see same page for IAT.

The MAP reads like this. 1.2vdc at idle

the 02 is near impossible to read with DMM as it changes too fast. (faster is better and new sensors do that)
my guess is yours will be stuck low. If yes, it will be very rich. the 0BD1 does that and is worse than OBD2,

a really fast and good dmm might get the MIN/MAX right. some DMM are slow, most cheap ones slower.
sorry out of stock, what i'd do, is prepay him so he's motivated , grin........
if keeping a pre 96 Track-KICK, HIS cable is good to have.
it's free software.
i think the Rhino cables were like 30 bucks??, nothing outrageous. (it's mostly just labor to make the cable, the level shifter is nothing expensive)
his is the best way: see photos here.

in 2007 i got mine to work in the bench like this. crude but works. and no software, only manual typing commands with REALTERM.exe

for sure having a scan tool is a blessing, tells you what the ECU SEES !
