So this is my case! Car is running fine but could go better! I put my van on the obd2 and came up with a mass air flow sensor code!I immediately started to work on it! I get correct voltage in the connector but I'm not sure what the ground should indicate! Should I check it with the volts? Ohms? Second what could be my problem if when I unconnect my maf nothing happens car keeps on going normally? I'm thinking a leak but could that just be it? Thank you guys!

Ok, was the sensor bad or was it the wiring at the connector? You check your ground with ohms. Not really looking for an amount. Your just checking that you have ground.
