ecu reports only dead maf not weak .
explained
the ECU uses the MAF for all fuel mix calcultation
it also watches (DTC monitors live) f
for stuck high and dead
and stuck low and dead.
both will set the 2 matching DTC codes.
example, 1:
if the maf should read say 3v at 70 hp engine power but is 2v you do not get that power level (it goes lean) but the ECU simply likes that wrong 2vdc level it is happy as a clam. (but not us ever)
'see?
