The code is specific to bank one. If the MAF can cause a lean mixture and is not uncommon on these vehicles. You may want to service the MAF to see if that helps.
Here is a link that explains how to do it:
Here is my problem. The code P0170 isn't relevant for this vehicle. I checked in two different manuals. See pics below. The code list is in numerical order and both professional manuals don't list it. Are you sure the code is correct, and the vehicle information is accurate?
Let me know. Also, let me know if there are any exhaust leaks, how the vehicle is running, and anything you can think of that may be helpful.
I attached a pic below identifying banks 1 and 2. Bank 1 is on the passenger side.
Take care and let me know.
See pics below.
