Thanks Merlin
The pics help me with identification of the wires. The first part of the question though, is the MAF sending a voltage or a frequency based signal back to the PCM?

I would say voltage, no testing that I know of instructs us to test for radio freqquencies! Testing always invloves volts, amps, or ohms.

Thanks again Merlin- I have read so many things trying to get an answer. In more than one instance I've read that some MAF sensors send a frequency back to the computer. I was searching about MAF sensors in general trying to find the info.
Thanks again Merlin.
