this ECU is not smart
it only knows dead maf, not weak or reading too high.
it reports DTC for stuck fully high or full dead. only.

my maf tests are simple.
voltage key on, no start is 1.0–1.6 volts , if not MAF may be bad.
idle voltage is. 1.7–2.0 volts. at 800 RPM, if not MAF is bad, or RPM is wrong.
if you gun the throttle hard wot fast the maf can reach 4vdc.
for sure flooding the car up any hill the maf can get near 4vdc. (max air is now) but if engine is weak we can not to that.
