Onslaught of CEL codes: P1800, P1572, P0113, P0183, P0011, P0021
 

For the past 2-3 weeks my '02 Maxima SE (89k miles) has been showing the 'Service Engine Light.' Since we just had a kid and my wife's not driving these days, I've been driving her car and this one's been sparingly used.

Anyway, decided to drive the Maxima to work today and brought my OBDII scanner along with me. Towards the end of the 60 mile drive to work the accelerator stopped taking inputs (revs dropped to an idle speed) for a few seconds. This happened maybe 4-5 times, which was pretty scary at highway speeds.

Pulled the codes when I parked outside the office and here's what I got:
Faults:
P1800 - VIAS Control Solenoid Valve Circuit Open
P1572 - Automatic Speed Control Device Brake Switch
P0113 - Intake Air Temperature Sensor Circuit High Input
P0183 - Fuel Tank Temperature Sensor High Input

Pending Faults:
P0011 - IVT Control (Bank 1)
P0021 - IVT Control (Bank 2)

I assume I'm looking at one issue causing these multiple faults, as opposed to multiple small issues but am not sure where to start. Any thoughts?

*EDIT* I should note that other than the accelerator issue the car runs perfect. Engine feels like it's brand new, no power loss, etc.

Check the engine ground.
I will replace the two camshaft position sensor
Both on the driver side

Both have a connector with green tab.
Press the green tab down to unlock and pull the whole connector
Camshaft position Sensor Bank 1 (near the firewall with straight connector with o ring)
Camshaft position Sensor Bank 2 (near the radiator with angle connector with oring.}

Crankshaft position Sensor (below the engine with straight connector with rubber o ring)
