CHECK ENGINE AFTER MAF CLEANING

[NewCivicRs]

Hi guys please kindly help.
I went to a honda dealer for engine & cvt oil change, throttle body cleaning and so maf and map check and clean if dirty.
So after that see the dashlight throws 3 sensors (VSA, EPS, PARKING BRAKE), I thought it will vanish after few miles driving but it won't away. So I disconnect battery for 25 minutes, remove MAF & MAP sensors to see if any damage and both are fine, no visible damage and connected properly. Take it for drive for 20 miles still the same.
It rides normal like usual, rpm is good, brake is good, high boost pull good except steering is lazy and won't turn to centre without help and feel slippery a bit.

Ktuner don't show any codes, I try to press delete all button couple times and it temporarily delete EPS and Parking Brake logo but soon after I take it for drive for few meters it turns back on.

Did I miss something here? Please help.

If it was an issue that came up after going to the dealer, I would take it back to the dealer, but I don't think cleaning the MAF and throttle body would cause a CEL for those things, but it could literally be anything since so many things can cause an issue and throw an error. Also, just so you are aware, you have a 10th Gen Civic, not an 11th gen.

Sorry my bad to be here.
I just look for other opinion, probably 10 and 11 gen have similarity in this case?

I was from civicx.com but seems no one has a clue about it.

I just saw you posted over there. Your post there didn't even mention that you took it to the dealer to have the the MAF and throttle body cleaned. I would try to cycle it a couple more times, drive around for a little bit, turn it off, wait and drive around again. Sometimes it takes a few cycles, check any connectors that may have been disconnected, and if the lights are still on and you actually just had service done at the dealer, I would take it back and let them know that issue came up after they worked on your car.

Yes I did it dozen times cycles start stop engine. I drove it to the mall, to somewhere else for over 30 kilometers on and off engine and still the same. Nothing changes then I disconnected battery, unplugged MAF & MAP sensor to see if any damage physically but seems normal and good condition, tighthen them up, check throttle body pipe, intake box, abs speed sensors on each wheel, everything tighten and plugged properly, nothing is wrong. After waiting for battery disconnected for 25 minutes, re-connect the battery and turn on the engine and still the same. Test drive again for few miles and still the same. Everything drives normal, I even drive really hard to try high boost 23-24 psi to see if it can make it and yes it can.

My apology did not mention about dealer visit on civicx forum and yes I want to bring back the car to ask for their responsibility but because tomorrow is sunday (maybe dealer is closed?) and this is night already, in the meantime I look for help here and there.
Hope anyone can help.
