Looking for Oxygen sensors
So I installed my SGT headers but had a heck of a time taking out the O2 sensors. The 2 post cat where a nightmare so I'm pretty sure I damaged at least one of them. After starting the car and idling it I got the SES, scanned for codes and got a P0140 (O2 Sensor circuit no activity detected (Bank 1 Sensor 2) and P0155 (O2 Sensor Heater Circuit (Bank 2 Sensor 1)......... so before I jump out and buy new just looking if anyone local has some used ones. I'm looking for 1 pre cat and one post cat on the long header.
Post cat Oxygen sensor Bank 1 Part #11781406621 Pre Cat Lambda probe Part #11787540167 This one I don't think I need this one but I'll just list it in case; Post Cat Oxygen sensor Bank 2 Part #11781406622 By the way I'm testing some defoulers with a mini cat inside so I hope this works, it will allow you to run headers without moving the post cat sensors to section 1. Thanks

Somewhat. I ended up buying a new Bosch post cat O2 sensor since that one looked like it was dead for sure. After running the car a bit I cleared the fault codes and now looks like I'm getting fluctuationg voltage from that sensor it so I think that fixed the P0140 (O2 Sensor circuit no activity detected (Bank 1 Sensor 2). I still have a pending fault on the other but I think it just has to do with the heater circut inside the senor which brings the sensor up to normal operating temperature faster on cold starts, so I think I might be ok for now but eventually I'd like to swap it out. I know this is might be too soon say but after clearing the fault codes, the SES (service engine soon) light has not come back, so the mini-cats look promising. I think the real test will be once the car hits the road.

I bought these ebay about 12 months ago when I ordered the headers. These are not branded.
