MAF Wiring

Post by jdifelice »

I am trying to diagnose a bad MAF. I got a multi-meter and ran the black lead to ground on the battery and probed the 3 wires in the MAF connector trying to find the hot and supply wires.

When testing with the multi-meter, none of the wires in the connector read the 5 to 12 volts expected. All of them read .03v. Does anyone know which one is the hot, ground, and supply wires? There are 3 wires in the connector.
