Troubling CEL code combo. Anyone ever seen this?

[TexasQ750]

Hey guys and gals. I have a 2015 whipple stage 2 on 93 octane factory whipple tune. 16k miles without a hiccup, until yesterday. It threw me 3 codes that won't reset.
P0100, Mass or volume air flow sensor A ckt,
P0108, Manifold absolute pressure/barometric pressure sensor ckt hi,
P0110, Intake air temp sensor 1, circuit bank 1.
Has anyone ever had this combo pop up before?
Only thing I did over the weekend was remove the front clip to fix a paint issue. Re-installed with no issues. I re-checked the MAF wiring harness again today and there is no pinching or disruption.
Any advice would be helpful.
Thanks,
Patrick

Definitely something to do with the MAF. I would trace the wiring as far back as possible and at the connector. If all is good I would replace the MAF.

If you have access to OBD logging, you can check and see if the MAF values are reasonable with the car idling, and when you give it a rev if it'll run. Also check the IAT display on the dash and see if it changes as it warms up. Also, unplug the MAF connector, remove and reseat it in case you bumped it or something, who knows.

Good advice here! +1

Thanks for the help guys. I will try all the above. If that doesn't work I have a friend with an extra MAF and will see if mine is bad. Thanks again.

Ruiner46 the funny thing is the car runs and drives fine. Even at WOT. My factory IAT stays right at 10 degrees above ambient while driving. That hasn't changed either. Thoughts? Thanks.

You could also try cleaning the MAF
