Mass air flow sensor?

Do all JKs have a mass air flow sensor?

My JK does not have the in-dash MPG display. I just purchased an OBD-II to bluetooth adapter, and I've been playing around with it. In the list of PIDs I am getting back, 0x68 (Mass air flow sensor) is not one of them. It could be the software I'm using, so I wanted to check with you guys.

I always assumed the MPG was just an dash display, and that the sensor was there on all models for consistency reasons.

We have an IAT sensor. Not a MAF. Unless the 2011 does that I'm not aware of.

I have an '08 :wink:

Any idea what PID the IAF is, or what IAF stands for? I'm not seeing that in my list either.

I don't know what PID stands for but IAT is Intake Air Temperature.

It's the little sensor in the hose of the stock air box.
