Chevy malibu 2018
 

Hello, so after buying my new car I noticed the air filter was very dirty so I went ahead and replaced it , after less than a day or so I got a code for Mass air flow sensor after I fixed the problem I deleted the code from the car system , now I have to get PA inspection I have already did two full drive cycles 300 miles and can't seem to get my oxygen heater sensor or EVAP ready . Does anyone know any specific way of making them complete and ready I just need one more to get ready .
please help me figure this out.

You will probably need to repair the oxygen heater code before the monitor for the evap syst will run.

I didn't have a code for it , this was just due to the system reset. Would it throw a code if it has anything wrong with it?

Was fixed just had to do a couple cold starts it took 3 days .
