Nanocom Results Interpretation Needed...

Just got my new Nanocom Evo for TD5 Defender - Nothing wrong with my td5 (or so I thought) but it is coming up with "1.7 air flow circuit (logged low)"
So, I checked plug on MAF and getting 12 odd volts to one of the pins. Have not done any more with that but went then to Evo again and looked at the gauges section and it reports 0.000 in following areas (stationary, engine running)
Airflow
Acell Track 3
EGR Inlet %
EGR Mod %
Wastegate Mod %

Is this just duff MAF creating all of this?, are these correct readings otherwise. As I said, truck drives beautiful and doesn't miss a beat

Thanks for any advice

ps - its a 1999

Hello, yes you need a new maf

Ok ta

Have you reset the fault warnings and then rescanned to see if they are still there, they might be historic.
