Check Engine light codes

[LiquidOC]

Check engine light came on after getting it inspected and getting all the "old" codes cleared. Got the oxygen sensor replaced (rear) because the link was physically severed. Anyways, new codes came up after about 100 miles of pretty light driving, and I can't find them anywhere. Okay, I looked again while I was trying to find the engine diagram photo, and I found them listed in the tech articles section.

Code 1:

P0170

Autozone dude said it was "Fuel Trim Malfunction: Bank One"

Tech Articles says: "P0170.....Fuel Trim Bank 1."

Code 2:

P1400

Autozone dude said it was "Secondary emissions system failure"

Tech Articles says: "P1400.....Manifold Differential Pressure Sensor circuit"

Code 3:

P0170

Autozone due said again it was "Fuel Trim Malfunction: Bank One"

Tech Articles says: "P0170.....Fuel Trim Bank 1."

Now, supposedly, I have to replace a sensor that sits right on top of my intake manifold: it's the sensor I've circled in the pic:

Think that would fix it?

Thanks!
