Downstream O2 sensor replacement - 2014 Toyota Yaris

[PantherFan88]

Hi guys, I am getting codes P0136 and P0137, bank 1 sensor 2. Planning on replacing the o2 sensor, but the wiring from the sensor go through a grommet in the unibody frame and I cannot see where the wiring harness is plugged into. Don't wanna pull too hard on wires. What's the deal with this?

I also was changing the belt and unplugged the camshaft position sensor because I kept snagging it with a wrench, forgot it plug it back in and ran the car for 10 minutes or so. Is this fine?

Thanks.

I posted the same ? with my echo years ago; if you remove the center console there will be a electrical plug to disconnect inside the passenger cabin, at least that is how the echo was configured.

On my old Corolla it was visible once you pulled up the passenger side floor carpet. My sensor was really tight. Took a big pipe on the end of a big breaker bar to get it off.
