Service engine light (Low MAF pressure) Friends 01 trans am had a service engine light on and the scan tool read it had low mass air flow pressure... What would this mean? Does it need a new sensor?

The description doesn't make sense, MAF does
not read pressure. MAP sensor does, it's at the
back of the intake. If it's reading low then it's
likely a wiring fault or a bad sensor. An intake
backfire can damage them. What is the actual
code number?

Ok so he said that the MAF read low voltage and something about one of the cats reading low efficiency dont really know.. He forgot what the code was becasue he did it really quick. Hope this can help. Thanks
