On the second diagram you think you can post or show the labels for each number to know where they belong? in the picture
What car is that picture from? Doesn't look like an Infiniti 2.0t engine layout to me. It's a MB 2.0t engine though.

These diagrams are for a 2016 2.0L Turbo. After staring at the diagrams some more, I think the manifold pressure sensor you're looking for is the pressure sensor downstream of the throttle valve (#16) for the "B" connection, not the pressure sensor downstream of the air filter that I referenced above.

#12 in this diagram is the pressure sensor upstream of the throttle valve which is what it appears to be the boost pressure sensor for the "A" connection.

98409


The exhaust camshaft position sensor is where your picture shows it (#6) for the "C" connection:

98410

98411

98412



As far as removal of the air cleaner housing, after removing the inlet and outlet air ducts, it appears that there are studs on the bottom of the housing that press-fit into 3 rubber mounting grommets. See below:

Wooow this is going to help me soo. Im surprised how helpful the q50 community is unlike the q60 community. Im still surprised you managed to get good diagrams. Also is there a special tool i need to buy to remove those mounting rubber? And also if their a one time use or can re install them again?

We aim to please. The diagrams are from the 2016 Q50 Service Manual. The housing appears to me to require removing the two air ducts and then pulling the housing upwards with some wiggling action. Simply center the studs that are on the bottom of the housing back on the rubber grommet holes and push down to reseat the housing.

Any type of tools to use to take off the air filter box out?
 
The inlet air duct has a couple of tabs that snap into the air cleaner housing and the outlet air duct has a band clamp that secures it to the air cleaner housing. A screwdriver should suffice. Go look at housing to verify.
 
This may help those guys that are looking to tune their 2.0T Q's

Good luck.

Q50 2.0T Tuning Options Video
Thanks for the link, I gave this guy the like (I usually do not give likes on YouTube). (Funnily, by the end of the video, there was a siren wailing, and bro looked momentarily aside with a concern. :) )

Yesterday, I was driving home from work. I jetted off at the lights trying to overcome an SUV with an aged woman driver in it, but my Q50 2.0t barely made it, and she was not even trying. When I came home and looked it up, the SUV turned out to be Alfa-Romeo Stelvio Q4, and it had a 2-litre turbo engine with 148kW and 330Nm. Or, it was the Veloce with the same engine upped to 206kW and 400Nm. It could also be the Quadrufoglio version (Q4 hints at that) with the 2.9t V6 engine and with 375kW/600Nm.

This made me thinking: "Hm... I need to tune up my Q50. Will JB4 be useful to me ?"

The issue is that I need to accelerate quickly from 0 to 60 km/h. My 2.0t takes 2.9 seconds. The standard 3.0t would make it in 2.5 seconds. The increase is not significant... how would the tuning be good for my purpose ?

Thank you! Based on your info I managed to install a tuning box for my Infiniti Q60 2.0T.

I remember when I actually drove one of these imo rare", cars,,at a very large used car dealership/600+ car inventory),,I fell for Q50s all versions RS,SS,3.7, and then I drove one that was very attractive looking,,but felt slower than my 16 Altima 3.5 SR,,,upon returning I saw the 2.0 badge on fender and realized that was the pretty significant difference! The tune I imagine provides more power making this another player in the line-up..
