Hi. I have a Honda Stream 1.7 (2001) with a D17A2 engine. Because of accelaration problems, I searched for the MAF sensor, but I havem't found it. Does this model have a MAF sensor or not? If yes, does anyone know, where to find it? 

Hi....welcome to the Forum

 

The 1.7 engine uses a MAP (Manifold Absolute Pressure) sensor to calculate the air flow and engine load and determine the correct amount of fuel to inject

Above is a selection if you need to buy one but also identifies what to look for in the engine bay.
Check that the vacuum hose going to it is intact and in good condition with no leaks.

 

Let us know how you get on with it all
