    check out page 96. The black connects to pin 17 on the ECU. If you measure resistance from black at the MAF to ground you are going through the ECU. For what it's worth weird resistances reading can come from measuring across capacitive and active devices. If the resistance "ramps" up or down then you are probably measuring across or through a capacitor. If switching the leads results in different, but stable readings then you are looking at a semiconductor. If you are at ground you should see a stable 0 ( minus lead and contact resistance).

      You should have had 1.2V from the white wire to ground when you had the car running. Check continuity across the harness from MAF to ecu. Check to make sure you have good electrical contact at the connectors. Triple check all ecu grounds. Reset the ecu and run the car. Check codes. If all that didn't fix it, swap the MAF. If you are still kick an MAF code, then replace the ecu.
