Without seeing your vehicle on my scan tool, it is hard to see what is exactly going on.
But, please allow me to share the following info with you:
The P-0171 code relates to the Mass Airflow Sensor. This is a VERY common code with the Corolla product.Your dealer *** should *** have inspected it for dirt contamination, and cleaned it, if it was indeed dirty.
Secondly, The P-0125 relates to Oxygen Sensor number ONE. If your dealer replaced the wrong sensor; (#2), you can expect to have problems.
My advice: unplug, remove, inspect & clean the MAF sensor. Ensure that the air filter is clean.
This should help you quite a bit.

p0440 code means that the evap system has a leak. This could be caused by a bad or improperly installed gas cap. Either that or the purge solenoid has failed or the canister is plugged and not working properly.

This fix comes from the service manager of a Toyota dealer, he is a online expert named Toyota Ed.
Toyota is aware of this situation. Production changes have ocurred to correct this condition.
Here is what you do: Take your vehicle to your Toyota dealer. Tell them that you have a P-0741 code, and you want them to apply "Toyota Technical Service bulletin TC008-04" to your vehicle. They will perform several tests, and if you vehicle is lower than 5 years old, and less than 60, 000 miles, they will fix it for free. This TSB is covered by the Powertrain Warranty. Additionally, Thay may replace the ECU with an updated unit, and that particular warranty is in effect for 96 months or 80,000 miles.
This will definatly cure your issue

I found several shops in my area, Albany, NY that had the older code readers. It worked fine, and cost me $30.00. It showed a bad O2 sensor that I replaced myself. I suggest you go to a reliable shop. Auto Zone/Advance etc.. do not have the right code readers. Joe
