Hi,

The MAF is on the air filter box right where the air induction tube between the air box and throttle begins. See pic 1 for location.

Before replacing it, I would suggest trying to clean it. Here is a link that explains how that is done:

Here is a link that shows in general how one is replaced. There will be two screws that hold it in place.

As far as testing, I need to know if there is a diagnostic trouble code that has been retrieved related to the MAF and what it is. Otherwise, there are multiple ways that things need checked. A specific code will point me in the directions of a specific test.

Let me know.

We replaced the MAF already. Looking for the MAP location. It's throwing the code P0068 and we've checked everything else. Thanks

Hi,

Sorry about that. It has been a long day. I attached a pic of the MAP sensor's location. Let me know if this helps.
