2013 Sentra P0101 PCV valve

I have a P0101 DTC in my 2013 Sentra SL, I have cleaned the Mass Airflow Sensor several times cleared the code and it ultimately comes back sometimes in a day or two sometimes in a week or more. Checked the air filter and filter box, it was shamefully dirty so I replaced the filter and cleaned the filter housing, also I had to zip tie the upper airbox tube because at some point I noticed the clip was missing and I searched to buy a new one to close the air gap from the tube to the filter box. After searching I realized there was no such clip and that the tube end has a molded in clip that must have been broken off, by I presume the dealership where I took it for a recall a few years ago, so I zip tied the tube to the air filter box. Ok that being done I thought I had solved the DTC but it came back a week later. Now after more research I am looking at the PCV valve and see there is a Technical Bulletin (NTB16-027) that suggest to change the PCV valve if it is colored orange. So I shopped for a replacement and all I can find are new orange ones. My question is why is the orange one significant, can I feel good about replacing the old orange with a new orange one? Is there another PCV valve I should be looking for? I have not yet cleaned or inspected the throttle body yet either.

The color represents the new design, you could try searching with the part number: 11810-6N202. There are some for sale on Amazon or at your local Nissan dealer. Due to the age of your Sentra, you should do the throttle body cleaning as well.

Thank You, I am looking into the throttle body cleaning now. The question I had about the color of the pcv was related to the NTB16-027 service bulletin that says to change the pcv if it is colored orange, but all the ones that fit that vehicle are orange no matter where I shop from. If the new one is also orange would that be ok?

I keep running a scan on the car everytime the DTC comes back and I see there is an out of range IAT temperature in my live datastream also my short term fuel trim B1S2 is at 99.219%

I am preparing to buy anew pcv and grommet , it is orange but that is all i can find that fits this vehicle.
It is driving me nuts.
Any other thoughts would be appreciated.
