Replaced both upstream oxygen sensors with new Denso ( from Amazon ) and now am getting both codes. I didn’t get them with the old ones, but they had well over 100k on them and wanted to change. I swapped them with new ones from them after returning and still have the code. Is it the sensors? Should I just go Delco. Where should I begin troubleshooting
