Check engine light question

[Intezgra]

Hey everyone!
I've never posted here so I'm not sure if this is the right forum for my question, but I just re-intalled my downpipes heat shield and a couple codes popped up.
I disconnected the battery while working on the car, and the only connections I had to disconnect were the oxygen sensor on the downpipe and the MAF sensor.
After putting everything back together I turned the car on but I forgot to reconnect the MAF sensor and I connected it while the car was still running.

Now code P0560 and P068a are showing.
P0560 system voltage malfunction
P068a Powertrain control module power source circuit unexpected voltage

Has anyone run into something similar? Hopefully I didn't screw up too bad

Thanks!

Yes, engine lights will pop when disconnecting and reconnecting sensors and battery. The newer Honda systems are very temperamental. If you have an OBD2 scanner you can force clear the programming or it will usually clear up after several longish drives.
