I’m gonna assume my Bank 1 Sensor 2 is going bad,a week ago I did put back my old upstream o2 sensor because my other scanner telling me is my sensor 1. I got a better scanner tool this time so I got some better reading. if someone know anything about Toyota data reading let me know.

Sensor 1 is the one throwing that issue. Good news, if memory serves that’s super easy to access, should be a twenty minute job. Sensor two is only a check for the catalytic converter, but the air fuel sensor is the upstream sensor.

Yeah I replace my sensor 1 with some cheap amazon o2 sensor then 3 months later my check engine light came on code P1130 and basically I just put back my old sensor 1 and that took my engine light off. I got a Denso downstream sensor on the way so I’ll read some live data again see if I see anymore dip below 0.1volt. Worst case I’ll just order a brand new denso upstream sensor 1 this time.

Sounds like a good plan - Denso is a good brand to stick with for sensors like this. 👍

Not really because of the price of 02 sensors. They can be pretty expensive
