Hello and thanks for using JustAnswer!
Thanks all of the fault codes are related to the mass air flow sensor.
Did you install a factory part from GM?
Some Aftermerket parts have been known to fail even when new.
I would inspect the mass air flow sensor wiring for any visual damage.
Also check the EMIS 2 fuse 15amp in the fuse block under the hood. This fuse powers the maf.
Check for a good ground on black wire with a white stripe at pin 7.
Awesome, i would check the fuse first.
ok next you will need a test light or multimeter to check for power and ground at the maf sensor connector.
pin 5 should have battery voltage. pink/ black
pin 7 is ground. black/white wire.
What ended up fixing the problem?
I will submit this to customer service.
