My Chevy Cruze 2014, has been having an engine light, after taking it to AutoZone, I got the following error codes : P1101, P0236, P227. AutoZone has advised replacing the MAF sensor. I have been wondering if the MAF is really faulty or it something else. After installing a used sensor that was taken from the junkyard (for testing purposes), the cooling fan started to run at a very high speed. I have then reinstalled the actual sensor, the fan does not run like before. Now I am thinking whether the MAF is faulty or not. Any thought? before purchasing a new MAF sensor at AutoZone.

MAF contains an intake air temp sensor. When unplugged with battery hooked up it defaults to screamy fan mode as a failsafe. Should go away next restart.
MAF codes are rarely sensors on these cars. I'd suggest looking for a vacuum or air leak instead.

@jblackburn, one of my AC line set had been taken out after the accident could this be the cause? I am planning to reinstall it, any advice? picture attached. Feel free to forward videos of AC line set installation.

No.
Look for a leak @ valve cover / turbo piping.
Is this a 1.4T? It's in the 1.6 section that was only available overseas.

I would try cleaning it before you buy another one. Buy a can of MAF cleaner though.
Chevy Cruze P1101 Causes
Engine Wiring– A good place to start is to do an inspection of the area around where the mass airflow sensor plugs into the intake. Make sure that the wiring doesn’t look broken or disconnected. You’d be surprised, in the winter months a rodent can cause a lot of damage to a an engine in one night.
Air Filter– Pull your air filter and see if something has gotten in there. If it has, remove the debris. Or if the filter looks very dirty go ahead and replace it. If enough air is not getting into the engine the mass airflow sensor is not going to get a proper reading, and P1101 will likely be thrown.
If neither the engine wiring or the air filter seems to be a problem, then it’s going to be time to pull the mass airflow sensor and see if it is dirty. A word of caution, these sensors can be incredibly sensitive to the oil’s on skin so make sure to use caution and not touch the sensor element itself.
Leaking Intake– If the intake seal on the Chevy Cruze has been damaged, there’ll be a vacuum leak. A vacuum leak means that air will be getting in to the intake not through the throttle. This is going to dramatically alter the reading at the mass airflow sensor gets and will trigger P1101.
A mechanic would be able to do something called a smoke test, which would let them visually see where the intake is leaking from.
See Chevy Cruze P1101 and P0171 Trouble Codes | Drivetrain Resource for more info.
Potential causes for this code to set are:
Vacuum supply
Pinched, collapsed or broken vacuum lines
Faulty control solenoid
Faulty PCM

A code P0227 may mean that one or more of the following has happened:
TPS not mounted securely
TPS circuit short to ground or another wire
Faulty TPS
Damaged computer (PCM)

I have noticed that the heater horse that comes from the anti-freeze reservoir is leaking, I purchased the replacement horse at Autozone, but for some raison it look different from the original horse I had on the car, I will go find an other horse and see if it fix the issue. I had a spill of antifreeze, is there anything I should be concerned about the spill?

The hose has been redesigned with another O-ring on the end of it, but should look pretty similar. Possible they gave you one for the other motor offered in these. That coolant junction it connects to has also been redesigned because they crack/leak often.
@jblackburn you are absolutely right. One question concerning the new O-ring, does it replace the U shape clip? image attached.

No, I believe the clip is still needed from what I remember.

Yeah, oily things just take a little while to burn off.
Hope that's the end of your leaks - for now!

@jblackburn yes, there is no leak for now I can definitely tell the difference in the way the car runs. But I still have the engine light to worry about, that will be my next project. thank you so much for your insights.
Which code is still present?
I have P0236, P1101 and P2227 , the Auto zone report says : "Inspect for correct air filter and air box is securely latch properly". The car had been in an accident, which had made the air box to be loose, I will have to find ways to securely latched it and see if there is any change. Any advice?
