MAFS wiring voltage

[nissandrift]

My car is running like my MAFS is bad. I checked the voltage on the wiring and the positive (black and silver wire) going in is at 14.5 volts. I'm assuming the white wire is the wire sending the reading and its coming out at 0.3- 0.5 volts when engine is somewhere between idle and 2500. And the black wire isnt putting anything and I assume thats because its the ground. Do those numbers sound right? I'm buying a MAFS before this weekend, but i want to make sure I'm buying the right thing. My engine is the stock KA24de.

anyone?

yeah your voltage readings are way to low. that should be the output voltage with the engine off. an intake leak beyound the airflow meter will also cause that voltage to drop drastically. make sure the intake accordian portion of the hose is not split in one of the valleys and also with that low of a voltage and the car still runs check to make sure the larger vaccum lines are all connected i.e. brake booster hose,PCV, ect.
