Check engine light p1101 keeps turning on and off? HELP!


I have a check engine light that will stay on for a day or two and then turn off on it's own for a day or two and then come back on and it just repeats this routine, I finally received my OBD2 scanner and plugged it, I get only one code which is P1101, I've read other threads that it's the MAF but appenretly it could be 10 deferrent things leading to this problem. Does anyone know if it could be the air intake ( I have a k&n typhon intake ) or the pcv valve or maybe the MAF sensor or ect...??

I have a 2011 cruze LTZ 1.4t automatic

btw My car doesnt shake, seems to be running fine. Honestly I've been having this check engine light issue for over two months, I had thought the whole time it was just a gas cap problem turns out it wasnt. stupid meee...:sad010:

Hopefully someone can help me out because I dont want to further damage the car if anything.

yes I had thought that to, but I made sure it was connected properly, maybe you could help me out with this question. I'm going to try cleaning it but first I was wondering before removing the MAF sensor do I need to disconnect my battery first?
just curious what if I dont want to return to stock anything i could?
Do you know if it's dangerous for the vehicle? I've been driving for well over 2 months with this check engine light comming on and off own its own..this problem started happening towards the end of winter ( March ), and I've had the K&N for almost 2 years now.
I want to fix the issue, many cruze owners out their have a K&N with no problems. I've had my K&N for 2 years and did'nt have a problem with it. I've been driving with the check engine light going on and off on its own because I read that it's most likely a loose gas cap (at the time) that's why it keeps going on for couple days then the light turns off for couple days then comes back on it own. so I did'nt think much of it figured it was nothing. Finally I decided to order a OBD2 scanner and found out that it's actually P1101, but this problem only started towards the end of March. So if it was the K&N the problem would'nt this have started 2 years after installing the K&N?

p.s I'm new to this forum as well as doing things to my cruze I'm trying to learn and start doing things on my own regarding it.
