2016 Civic EX-T

[SHolmes]

I flashed back to stock and unlocked but have repetitive codes that will not go away , I have done a few times , disconnected the battery before each attempt . said Civic has a PRL short ram CAI , Map stainless high flow exhaust and a PRL Flex Fuel which I have not set up . It keeps giving me a oxygen sensor heater bank 1 sensor 2 code ( P0141 ) and Software incompatibility with Engine Control Module / Powertrain Control Module ( U0301 ) when I try to erase it states Command Rejected ........ any help would be appreciated .

Is this only when returning to stock from the online menu?

As far as I know ... even after the parts and flash done the check engine light was always on ... I need an inspect and cannot get those 2 codes off since parts and flash . I'm an old school V8 kinda guy but was amazed at the power the lil Hondas put out .... not so much presently

Are you uploading a 16, 17 or a 16-17 calibration?

[SHolmes]

When asked first about returning to stock there was a prompt about it can only go back to a 2017 stock flash but it did not after that ....

[SHolmes]

Is there any truth in Honda releasing a software update to the CVT that needs to be done by them .... and is the high flow down pipe causing the o2 issue ...

[SHolmes]

Why can I not delete codes with a scan tool , after the flash it states command rejected ...

When you upload a calibration what year calibration are you uploading?

[SHolmes]

2016, is there an easier way to communicate ..... Ive tried calling no resonse

Upload a 2016-2017 calibration and that should work, as it sounds like your vehicle has the oil dilution update from Honda and they updated the transmission controller to the 2017.
