There’s always a chance to throw a code for something. Any code during this maintenance job can probably be cleared by disconnecting the positive battery terminal if you don’t have a code reader or TechStream.
I added those codes above because we couldn’t add any attachments in the recent thread on throttle body issues. Found here…

This job is pretty simple. The important points would be:
Do not touch the MAF wires inside the sensor and use the correct cleaner.
Don’t use a brush, paper towels, or rags on this part either, just keep spraying the crap out of it if it’s really dirty. Mine was pretty clean to begin with.
Be sure to let the MAF sensor dry before installing.
Use caution when disconnecting and reconnecting the vacuum, coolant, PCV, hoses, connectors, clamps.
I’ve seen a broken connector on someone’s TB in a how-to vid.
Don’t drop anything downstream of the TB. I wouldn’t try to clean in there either.
You can use rags and paper towels on the TB but use care when opening the butterfly. I think I’ve seen someone say don’t open it at all. Seems a bit dramatic.
There’s a bunch of pretty good vids on YouTube from Toyota mechanics and DIYers I recommend you check out first.
