I will try to take a better pic. And what is an ambient air temp. sensor.
Thanks

RE: What is this?
outside air temperature sensor... Senses the temperature of the outside air... Typically this is clipped to the latch support in front of the radiator. That is if I am correct...

RE: What is this?
I agree on the air temperature thing, it looks like the one on my truck. As for the box in the rear I am not sure what it is but I think I have one on my truck too, maybe has something to do with the fuel deliver system or airbag stuff or something. No exact idea.

Oh, had no idea. Thats sort of sweet I guess. Is there any way that that might malfunction and cause gaus fume smell while driving? Or would that be something else.

Technically yes. It is the EVAP canister. It contains charcoal or activated carbon.
Evaporative Emission Control System - General Information
The purpose of the Evaporative Emission (EVAP) control system is to prevent the fuel vapors from escaping into the atmosphere. The EVAP transfers the fuel vapor from the sealed fuel tank to an activated carbon, or charcoal, storage device, or EVAP canister. The EVAP canister stores the vapors until the engine is able to use the extra fuel vapor.
When the engine is able to use the extra fuel vapor, the intake air flow purges the fuel vapor from the carbon element, and then the normal combustion process consumes the fuel vapor.
The system is designed to detect the evaporative fuel system leaks as small as 0.040 of an inch between the fuel filler cap and the purge solenoid. The system can test the evaporative system integrity by applying a vacuum to the fuel tank in order to create a small vacuum. The Vehicle Control Module (VCM) then used the fuel tank pressure sensor to determine system integrity.
