OK and I think I see the problem I took a picture of all four sensors notice bank to censor one which I believe is the upstream I see that there is no power going to it ?



I have never even seen it before LOL but I took pictures of all 4 sensors notice how Bank 2 sensor 1 shows no power

Yes, there's a starting point! I'm surprised it did not throw a code for a failed sensor. Check the wiring and a cheap way to test that sensor is to swap upstream sensors. If the problem moves to the other side, you know it's the sensor and not the motor.

Crazy thing is this morning it did throw a o2 code so when I did switch them it indeed moved, so I changed it out. I replaced both of feb this year with a delphi so it’s weird it went out again. But no more light and no rough idle now, I got a denso from Autozone so let’s see how long this last

I appreciate you help pointing me in the right direction
