  1. Did that work completely for those codes? My 06 Legacy is throwing the same codes. I have swapped out the down Stream O2 censor, changed the sparkplugs, and wires, changed out the mass air flow censor as well. But the codes keep coming back on after about 250 miles.

     

    Yes it did, its been about 300 miles and the car is running better too, I made sure to order a Denso sensor because it was the oem replacement and I have had problems with cheap sensors in the past.

  2. 2009 Legacy, basically stock. It Started with getting a an intermittent P2096 "Post catalyst Trim System Too Lean Bank 1" And could smell it running a little rich

     

    Eventually code became consistent and ran very rich. Then it progressed and started throwing these codes

     

    P0137 " 02 Sensor Circuit Low Voltage Bank 1 Sensor 2"

    and

    P0031 "HO2S Heater Control Circuit Low Bank 1 Sensor 1"

     

    And now finally it's to the point where its causing a misfire in cylinder 1.I replaced both the pre and post cat 02 Sensors which didn't seem to help. So anybody got any ideas on what to check next?

     

    Did you replace the sensors with OEM replacements? just asking because I had a similar issue when replacing my front O2 with one from Rockauto, replaced it with an oem on and my issue was gone.

  3. What's going on guys, this is my first post on the forum!

    I tried looking through threads to find some information but couldn't find what I needed. The car is throwing a P0137 (Rear o2 low circuit) code along with a P2096 (Post catalyst fuel trim too lean). When I read the voltage on the AP it hovers around 0.00-0.02 but has occasional high spikes. My AFR is good though and I checked the o2 wiring to check for a poor connection but it checked out. I'm pretty sure it may be just a bad sensor but I figured I'd ask around first.
