So few weeks ago I had the po121 pop up and I cleared that code. Light came on last night, borrowed a code reader and of course it’s a different code. What should I look for in the live data readings for this code. Seen on google that it might be the oxygen sensor bank 1 sensor 1. Before I go changing it out I figure I should look for live reading.
