2018 civic 1.5T Limp Mode

[Jclrk279]

I recently had some error codes pop up and cause my civic to go into limp mode. About a month ago it started. I took it to Honda they checked it out and said it was the O2 sensor. They replaced it, the codes were gone and it seemed to run fine for a couple weeks. I have the +3 map loaded and always run premium fuel. Yesterday on the way home I was at a stop sign and as I proceeded through the stop sign it went into limp mode again. I could only go about 5mph. These errors came up PA 18; DTC U0100; DTC in a square box: 27, 30, 33, 42, 60, 103, 112, 113, 118, 119, 128. I took it back to Honda last night and they said it was likely from the aftermarket RV6 catted exhaust/frontpipe and I would probably need to get it dynod. Anyone else have a similar issue? I'm pretty sure it's not the exhaust cause I've been running it Since May of 2019 and never had this issue until now.

Unfortunately I wasn't able to get it datalogged while the errors were there. After I got it back from the dealership their were no errors but i decided to datalog and drive around in town and on the highway, to see if anything came up again. Nothing did but here is a link to my datalog, maybe you can see if anything looks abnormal to you.

Without any error codes, there is nothing really to give us more info. If it happens again you need to datalog and see what errors are reported.
