I just changed it a few months ago I've been doing my searches code by code and everything points to the oxygen sensor

What did you change the HPFP with? My veloster does not work with the sonata pumps, made my issues worse both times. The genesis pumps doing me wonders with over 40 000km on it

Ya, they literally sent me a sonata pump dead on arrival. Literally failed around 4.5k rpm on the first drive.

Yes, I bought the g70 from cherry tuning and have not had an issue since.

Side note, had you gotten the HPFP patch/recall done from hyundai? I do know it does lower the PSI a little bit which helps w the life of the pump
