Had my car listed above tested with diagnostic and it came back as a bad mass airflow sensor. But now I hooked it up and it’s showing me code P0776. So, do I need to change the air sensor or just do that solenoid be in the transmission? Here’s what they ran first on car showing codes. But now it reads code P0776. I’m confused any help would be appreciated! Thank you

Were there any codes for the MAF sensor? if not, I would concentrate on the code P0776 which is:

P0776 code indicates an issue with the Pressure Control Solenoid B (Performance or Stuck Off) in the transmission.

So, this can be because the fluid needs to be serviced, or the solenoid is bad. Either way let's remove the transmission pan to inspect the fluid and check out the filter for metal, I can tell you these CVT transmissions have many problems. Here is what we need to do to see what is going on. If the fluid looks okay, I would get a rebuilt valve body and install it, then clear the codes. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.
