HiCustomer Thank you for asking your question on Just Answer.
Did you happen to write down the EXACT error code that is turning your light on?It should be 1 letter and 4 numbers.
I did check on the MAF, and the manual says "The mass air flow (MAF) sensor is an integral part of the throttle body assembly and cannot be serviced separately."
I am not sure how the MAF became suspect, but the EVAP system will definitely cause problems if it is not functioning properly. Here are a few PDF files, that you should be able to view on your computer and print. These will describe the system and the two codes you gave me.
Here is the main schematic that goes along with the error code testing procedures and a couple of diagrams that show where the main components of this system are.
What I would do is have that EVAP system checked and fixed. Again, if it is not working correctly, it could be causing the engine to not run properly, because the control systems will not be feeding the correct amount of fuel into the system at all times.
Once the EVAP system is functioning properly, the codes should be cleared and the system should perform better. Then if there are any remaining problems, they can be addressed.
I hope this helps. Please let me know if you have more questions.
Take Care, Greg A.
