Hi guys,
I’m looking for some help/advise with my 2019 2.0. I did a CTR swap with CTR downpipe and hondata tune which came with the flash pro. I have a Check Engine Light with code P0133 which is for the o2 sensor slow to response bank 1 sensor 1. I have checked over all the intake and exhaust for any kind of leaks. Reset the light and it keeps coming back after 13-14 days of driving. Finally I replaced the o2 sensor with oem and it seems to be still coming back.
has anyone experienced this? Any info will help.
Thanks.

I tried looking into flash pro, only option I saw was to bypass the primary and seconday sensor. I wonder if a custom tune can help with the o2 sensor issue.

Ya I did. They told me to follow Honda service manual for diagnosis. Very disappointed with their response. It’s obviously the tune as a sensor can’t work for 14 days and then act up. Kinda tempted to change my car but I really like the car.

I didn’t do that as I’m running a type r turbo so it might cause the engine to run lean/rich. I am going to get a pro tune and hopefully that will resolve the situation.

Thanks, for sure I will let you know how it goes. Also this way I’ll end up getting some dyno numbers running CTR turbo and downpipe with hondata off the shelf tune vs pro tune.
