Hello and thanks for your question. My name is XXXXX XXXXX I will do all I can to help.
Let me first ask, The P1472 code, that is the code that is stored first correct?
and the P2071 is the second code read off from the scanner?
A Transmission Specialist test drove my Fereelander. Before the test drive, he found the code: "61472 = Intake Manifold Actuator" stored in the ECU. He cleared this code. During the test drive a different code showed up o the scanner: "62071 = Intake Manifold Timing". The "Check Engine Light" has not shown yet.
Alright, Most likely the VIS motor has failed, but first check the wiring to and from the VIS motor's with your P1472 code, I would check the VIS number 2 motor first. (There are 2 total). and they are called Variable intake manifold system motors. or VIS for short. They are on the intake manifold, here is a picture. You may want to pull the motors off, check the linkage, and be sure nothing is loose or the square peg on the motor isn't broken.
