Question

does a 2002 gmc envoy have a mass air flow sensor.

Answer 1

It uses the MAP sensor, BARO sensor and intake temp sensor to do the same thing. (see picture below)

you can try to clean the map sensor and intake temp sensor with mass air flow sensor cleaner. A dirty throttle body might also set the code on.
