Hi all, im trying to figure out if my Mass Air is bad or not.

I have these values (see pic) when engine is off but ignition in on position.
Can you tell me which Voltage value I should be looking at, Intake Air or Air mass sensor 1?




Reason i'm asking is because i'm getting "implausible" errors on MAF when outside temp is less than 50F or so. I think it cant adjust to larger airflow properly.
I have EvoM intake and 82mm TB. I'll be getting a tune but want to make sure everything is working properly to begin with.

Any info would be greatly appreciated.

The last row and it looks normal if you are talking about air flow. At idle with engine fully warmed up, I think the MAF should read around 17-19 kg/hr.

The MAF also meausres the intake air temp which is indicated as intake temp in Celcius directly. You should be able to just read the temp and see if that makes sense.

thanks for the info, i'll take a look today after work to see what values its pushing.
also can anyone tell me if this is normal?
