Can anyone help me figure out why on my 2018 Civic SI keep getting CEL regarding O2 sensor? The code p0134 keeps popping up. I got an Invidia exhaust, PRL Front and Downpipe, oil catch can, AEM short ram intake, and Ktuner (Tuned by Derek Robinson).
This CEL only started showing up after the Front and Downpipe and the tune. I kept clearing it since I didn't think it was much of a big deal. Now I went to get my car inspection and couldn't pass because of OBD Readiness Monitor Results. Catalyst, Evaporators System, Oxygen Sensor, and EGR and/or VVT System showed as not ready. It only reads as Ready after 40ish miles except for EGR and/or VVT System.
I talked to Derek Robinson and he recommended to change the O2 sensors so I did and the p0134 code still comes up but less. Also, I put my car back into factory tune and driving it 300-400 miles as per recommendation of my friend who is doing my car inspection.
Anyone got a clue on why this happens and the possible fix?
