Hello Shaiba, sure, just look at the comment right below your comment from Sean.

This will apply for most Toyota MAF sensor from models from 1999 and later.

Hello Sean, thank you for your great feedback.

Hi,
I have 2000 Toyota Echo and having similar problem. My car would hesitate for few seconds when sometimes I press the accelerator especially when it is not warm enough.
Should I try the same thing.
your wise advice is needed.

Hello Nella.

The Aveo does not use the MAF (Mass Air Flow) sensor. It instead, uses the MAP (Manifold Absolute Pressure sensor).

If you still need to find the MAP (not the MAF), then it is located in the plenum, which is the part at the rear end of the air path, and it has 3 wires; WHITE, LT BLUE and LT BLUE.

This cars base their fuel delivery calculation on engine load by measuring its absolute pressure instead of basing it on air mass flow as their counterparts that use MAF sensors.

Best regards.

@Jenny If you want to try the cleaning in your car, it would be similar. Just spray the chemical in the apertures of the sensor while uninstalled and leave it to dry completely before putting it back. The location of the sensor is drawn below. Cheers.

Hello guys. I’m in El Salvador Central America, I’m really thankful with you, I own a corolla 03, brought from the United States, my car was hesitating when I accelerated, was hesitating so bad that, if I was stopped, then pressed the accelerator deep to the floor, the car would died. then I read your article, and I did ecxactly what you say, and the car runs like new now, thank God that here in El Salvador there is a store that sells CRC products, including the QD elactronic cleaner spray, so I want to thank you so much, I’m so happy, you saved me a lot of money.
Too bad you don’t have any articles about the corolla 98, I also have a corolla 98 and just stated a little jerky motion at all times, in Idle and when accelerates it’s not a smooth acceleration, can you please help me in that one too, you article was so clear, including the pictures so understandable, I wish the other guys can put pictures like you.
Thank you soooo much
Whilliam from El SAlvador.
