I believe I did get the oem sensor. At least it’s the one Max Capacity recommended and from my research it is oem.

Hey guys just got the new o2 sensor and I think I’m going to have to splice in the female connector. Is soldering the connections ok to do here? I feel like if I do it closer to the connection side it won’t get nearly hot enough to melt solder.

Thanks Scotty the difference is that I’m getting just the one code. I think I might just bite the bullet and get a OE Denso then continue down the flow chart. I’m really curious to see how fuel pressure and other systems are behaving. I just got stuck on this resistance issue, started breaking into a beautiful wiring harness and getting overwhelmed. Wanting to fix the resistance issue I just have no idea how. The wires quickly become lost in a massive bundle that’s really well packaged.

Funny you guys say that, I just replaced it about a month ago with oreilly Denso. Can their product vary that much?

Mods list below.. so I was cruising at about 40 in fifth gear when the check engine light came on. Pulled over immediately and checked it to find a PO2096 thrown. I have done an extensive amount of research and found a bunch of people going down the route of replacing sensors and such with no Avail. I figured before I go the same path I should go into the manual and start down the flow chart Subaru has provided. At step 5 (I believe), they had me check pin 8 and 9 on one of the connectors at the ecm to ground...pin 9 was below the specs at 1milliohm. The suggestion was the fix the ground fault short in the harness between the ecm and front O2 sensor. I am looking at the harness between the two and it looks flawless. I started with some simple connection areas that may have been suspect but they are so clean and nothing has been disturbed. I really don’t want to start breaking into this wiring harness if nothing is wrong with it. My questions are, is there something else that could be causing this? A poor connection inside the front O2, something in the ecm. Where might I even start looking for this ground fault? Should I assume it’s good and move to the next step? My resistance is in the killiohms on either pin 8 or 9. Cant quite remember but one is within spec. If someone with time could measure theirs? I don’t expect it but worth a shot. I have also been experiencing fluctuations in a/f ratio at idle so maybe I’m on to something. Maybe some suggestions on where to start looking. I’m just rambling at this point. Thanks in advance.
