RE: Frequency Efie Maf Issues
What does "gs" mean?

It's unlikely the unit is defective. We test each one before shipping it. However, failures, while rare, do happen even after the testing.

Are you certain you have a frequency type sensor? Using the frequency mode for a voltage type, or vice verse, would give some very odd behavior.

With the 2 pots, if you are adjusting the fine tuning pot, that is a very very small change occurring. So if your readings are jumping all over, I've got a strong feeling you are on the wrong wire, or the wrong type of MAP signal.
