Yep, do it all day. You need a meter. Have you tried the SAFC2? Select the KVAFM screen and check for any action there. The wires are probably very brittle (thanks turbo!) and they tend to break because the afm is mounted to the chassis and the wiring is mounted to the engine. There is some movement between the two. Visually check the wiring very closely, look at the pins both in the sensor and on the connector. Give each wire a gentle tug at the connector (found most of them this way). If the wiring checks out visually, start doing the meter tests. If you have any problems or questions, well...you know how this works.
