verifying good MAF sensor.

[discograham]

I am looking to verify my MAF sensor is good using data from ultra gauge. It displays some data labeled maf, but I don' t know what it means.

At idle "Mas Air" reads 6.870 and at 1500 rpm it reads 11.4.

Another sensor labeled MA2 g/s reads 7.391 at idle and 10.45 at 1500 rpm.

I have a 2004 discovery and have codes 1174 and 1171.

Thanks for any information you can offer.

No information, but nice full-size jeep in your avatar!

Thanks, it sits in the garage too much because I am always working on my Land Rover!

When my MAF went bad the scanner read 0.00

Mine sits on the street... because the garage is filled with Land Rovers!

Is this with the engine fully warmed up? I'd have to check, but that seems low. Are the tabs for your air box lid broken?

I'd say the first step is ask Discoweb. For sure.

No it was not fully warmed up, my air box is good.

Well of course, I thought I would give Discoweb a try!
