Thanks.

Get coolant temp sensor checked.

Get the coolant pressure tested, its definitely leaking coolant. You will need to get the coolant running line.

Pressure test will help you to know from where exactly coolant/refrigerant is getting leaked.

Your corolla doesn't use a MAF sensor, it uses a MAP sensor

The map sensor is located on the Intake Manifold right by the throttle body. That could easily be causing the issue you're stating.

Enter the code in a Google search box and it will bring up a list of articles on the trouble code, such as the following:
A code P0171 may mean that one or more of the following has happened:

• The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
• There could be a vacuum leak downstream of the MAF sensor.

Possible Solutions Possible solutions include:

• In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner . Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
• Inspect all vacuum and PCV hoses, replace if necessary
• Check for a dirty fuel filter and proper fuel pressure

inside the air intake between filter housing & engine.with ignition 'on',check for 12 V at wiring connector to sensor--BLK wire + BRN -

p0171 is lean condition bank one. you could have a vacuum leak a bad map sensor bad maf sensor clogged fuel filter low fuel pressure. start with the vacuum leak first.
