I've been watching the mass air flow over the last couple of weeks and now recently had a P0101 code for not enough air at the mass air flow sensor. The reading that I'm getting at me idle with the engine hot is 10 g/s (I believe the number for health rockers is 15g/s?).
I did go through the diagnostic procedure in the FSM and checked out the boost hoses and didn't see anything wrong with them (I'll be replacing hopefully soon anyway) but they seem to hold pressure fine as boost pressure tops out around 20psi (I do have a low boost issue to that I'm checking out).
After looking at the hoses I cleaned of the MAF sensor and checked the circuit. The MAF sensor was dirty but cleaning did not fix the issue. One thing that I found was at the MAF sensor connector, I should have 2 readings of 5v. With the ignition on I only have 1. Pin 6 has no voltage. I did oh out this specific wire also and have good continuity.
I didn't find a real good explanation of how the sensor works. Should there always be 2 5v signals applied to the sensor? What are your guy's thoughts here?
