Rear 02 Sensors, which are direct plug and play

[CanuckQx4]

Hey guys, my car is throwing codes for both rear 02 sensors.

I believe it was p0138/p0139, p0158/p0159

This would surely point towards both (assuming original) sensors have gone bad, assuming they are connected properaly or is there an error I could have done to cause all 4 CEL's?? The plug for our sensors is quite large and Im wonderring if there are any specific part numbers or brands I should buy that are direct plug and play to the factory connectors, I would like to not have to do any solderring.

Luckily when I had my engine out I unclipped most of the hard to reach clips so this job shouldnt be to hard assuming I buy correct fitting parts

It is odd to have two O2 sensors fail at the same time. It can happen, but I would say it would be pretty unusual.

In addition to O2 sensors, they also list fuel pressure, injectors, and intake air leaks as possible causes, all of which make the engine run lean (EC-268).

Might be worth putting the car on a scan tool and looking at live data given you have a P1110 also.

I also got P0158 a while back. I cleaned it about 3 or 4 times, and it hasn't come back yet.
I bought one Bosch sensor but don't want to replace it if code doesn't come back.
