MAF help
Hi guys, I wonder if anyone can help with a little information?

I currently have my car stuck in limp mode and on the code reader some of the codes are
P0100 Mass or volume Air Flow A circuit
P0102 Mass or volume Air flow A circuit Low

also on the data stream it shows MAF g/s @ 0.00.

Firstly can anyone shed any light on this?

I have checked the wires with my multi meter and one is ground, two read about 5v and the last seems to be inconsistent, this is the same on both MAF sensors
Are these readings correct?

I would appreciate any help or advice

5V looks to be OK for MAF signal wires, 12V for the other one. Did you fix this issue with swapping MAF sensors?
