Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I am running the OFT flash and have tried numerous times to get OFT to respond to help set wider parameter for the sensor; no luck.

I cut the OEM plugs and used the tricky splicers that supposedly allow oxygen to pass along the copper conductors (true ?).

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Thanks for the info, albeit not good news...well NY doesn't test emissions per se but the darn O2 code likely wont fly.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

Post-Cat O2 (Bosch 'Universal') Sensor Wiring Diagram Well I guess I stumped the band on this one. An answer in-hand from a trusted vendor so I will share: ================ Cylinders 1-3 (cyl #1 is closest to the passenger on US drivers) BK/YE Voltage Positive YE/BN Voltage Negative RD/BK Heater Negative BK/BK Heater Positive Cylinders 4-6 WH/GY Voltage Positive BU/BN Voltage Negative BK/RD Heater Negative BK/BK Heater Positive =============== Hello friends, firstly I thank you for all the valuable posts I've read through the last 3 years. But secondly, I'm stumped... Well the AOS finally went on my 2006 CS, making the Jeep that was tailgating me disappear...along with the 3 cars behind him!! Oh well, thanks to you guys, no panic, I expected that to happen. It was time, so I replaced said AOS, plugs/coils/ and installed one of the first offered SOUL 987.1 catted headers they whipped up for me to connect to my SOUL cat-back already in use. So BN cats too. Purchased the Bosch OEM O2 sensor up front and in an effort to save money, got the 'universal' Bosch O2 sensor for the aft spot. Yup a mistake trying to save money I learned. Bosch offered no wiring diagram for the CS. I cut the OEM plugs and used the tricky splicers that supposedly allow oxygen to pass along the copper conductors (true ?). Something short of a wild guess on how to wire them in terms of color code. Over an hour search & many days led me to frustration on learning how the simple 4-wire circuit is supposed to be wired. At this point, I'd order the 3x more costly OEM ones but I lopped off the connectors already. Well I put it all together and took off with no CEL indicated until I shut it down for the first time. Dang! Thanks guys!

POST 2Original post

I too have the Soul Performance Catted HEaders and love all about them. Replaced all 4 O2 sensors when I did the headers and still have the after cat O2 code. I am running the OFT flash and have tried numerous times to get OFT to respond to help set wider parameter for the sensor; no luck. There customer service has gone to S*@t for Porsche . I am looking to add these spacers: https://soulpp.com/product/universal-o2-spacers/ to see if I can tune them out. Please post if you use them and let us know if they work. If I get them sooner, I will post. BTW, I live in Florida; no emissions testing. Good luck.

POST 3Original post

Thanks for the info, albeit not good news...well NY doesn't test emissions per se but the darn O2 code likely wont fly. I agree, that SOUL setup is excellent. The headers were so well built that I didn't even have to loose the existing cat-back system to install, they were that precise! Perfect real world drive-able sound too. (no I don't work for them haha). Any other tuner ideas are welcome, she's running stock tune at present.
