did you use OEM o2 sensor???

No I ordered it tho just waiting for it to arrive... you think that is the problem??

[riceboy88]

p0102-massair flow circuit problem
p0340- camshaft sensor problem
p0101-massair flow problem
p1157-a/f sensors aka o2 sensors.

one problem could cause all these codes. since you said something bout the o2 sensors i would try to fix that first. camshaft sensor code idk. you may have to take it to honda but it could be caused by one of those other codes but not sure.

can you just take it to the dealer to check it out as warranty work?

Finally benji asking for help.

do you have an aftermarket intake or is it factory air box? If its aftermarket most of those code but the 02 codes indicate mass air flow and intake problems. they wont have anything to do with the 02 sensor. and when you replace the 02 sensor you will need to do a ecm idle learn procedure in order to properly calibrate the sensor. then you need to figure out about the rest of the codes. the reason your car was in (limp) mode was because there is a problem with the cam position sensor on your intake cam.
