Mass air flow sensor location on a 05 Envoy 4.2

purchase MAF sensor, Auot zone shows MAF is on the throttle body, car does not reflect that. Purchased Envoy book, it does not show a MAF or provide information how to change it.
Thanks

a mass air flow sensor measures the air movement going into the throttle body. so it has to be mounted between the air filter and the throttle body. If you have the part look at the plug in and see where there is a connector like that in the air filter box or the tube that goes to the throttle body. does your vehicle use a MAF?

why are you changing the mass air flow sensor? do you have a code number?

No code reflected
