The exact shape and size of the MAF sensor will differ slightly between Toyota models. Its location is always between the air filter housing and the throttle body. Consult your owner’s manual if you are unsure where to install.

Depending on your Toyota model, you may need to use a screwdriver, or socket set to remove the screws or clamps securing the MAF sensor in place.
