Not sure if a fouled / malfunctioning MAF sensor would always set a CEL.
If there's no reading from it at all, then probably yes, but if the
voltage is fluctuating and incorrect as described in the link below,
perhaps not.

Which refers to a later model, but still a GA 16 DE engine, which when I
look at posts above is what you seem to have (my mistake - I thought the
GA 16 "DE" was introduced later than '90/91).
Are either of the distributors you have dirty inside from oil leaking
from the internal seal on the shaft? (not from the main O-ring seal
between the distributor and rocker cover) That's also a common problem
once they've got up there in mileage, and contrary to what Nissan told
me, relatively easy and cheap to fix yourself.

Let's see it move. Note the minimum wheel spin with its launch control
system.
