Check Engine Light Problems
So I'm like way overdue for inspection, been driving around without a sticker for about 3 months now, and I still can't get rid of my CEL.
First it was B1S1 O2 Sensor problem, I replaced that then B1S2 and B2S1 came up. A few weeks ago I replaced those two sensors and the rear struts and I cleared the codes. I drove to the gas station and filled up and when I got back into my car my CEL came back on. I didn't have a chance to check the codes until this past Saturday and the codes on my scan tool that came up were:
P0150 B2S1 Problem - Four Key Cycles since Failure (not sure what that means)
P0105 Absolute Pressure Sensor Circuit Fault
P1105 Map/Baro Switch Solenoid
Since almost all the codes that came on had something to do with a wiring problem or a loose connector, I checked those first.
The connector circled in yellow wasn't clipped in even though it was all the way down, so I bent the clip back a little bit so it would be able to click in and stay put.
The area circled in red I found a hose where the clamp was actually broken and moved off of the end of the hose, and there was a small hole in the hose with a greenish liquid on top of it. I'm not exactly sure what the hose was for but it was about 7-8 inches long. When I went to go remove it and replace it the end with the broken clamp actually crumbled away.
The bottom of the picture that is highlighted in green is where the O2 sensor connector is (the picture doesn't go far enough to be able to see it, but it's like the first connector you see above the radiator). I knew from when I replaced the O2 sensor that whoever had this car before me broke the clip, so this time I wrapped it with some electrical tape so it wouldn't go anywhere.
I cleared the codes after doing all that and I drove the car around for about a day, and then they came right back on
All of these codes haven't affected my cars drivability or performance in any way, so I'm assuming it's nothing major, I just really need my inspection sticker so any help in removing these codes would be great

You will need to download the FSM for you to understand what those codes mean. None of the parts you checked were anything related to the codes you have. Anyways, I will help you but unfortunately, I cannot edit your pic so I will have to explain my best.
P0150 - Front Oxygen Sensor Malfunction - which is the left plug of the green line drawn at bottom of page
P0105 - Absolute Pressure Sensor Circuit Fault - located next to nissan front cover with those two rusted screws. That is the sensor that needs replacing.
P1105 - Map/Baro Switch Solenoid - located under the valve cover hose going back to airbox. It is the one closest to the tranny dipstick.

Super late reply, but assuming that the first code is just a loose plug, to get rid of the other two codes, would simply replacing those parts fix my problem? Also does anybody have a part number for those parts, or a link to where I can buy replacements?

Yes, replacing those other two parts and clearing the codes after replacing will fix your problems.
