after install i pulled both ecu fuses for about a minute. replaced and drove for about 10 mins. codes returned and i rechecked. still getting code 41. i have the f22a1 with h23 im and pt6 ecu. the o2 sensor location is on one of the four runners on my header (like dc sports). the stock location is at the collector where all four come together. could that cause a read error? i purchased an exacted replacement for the f22a1, delco brand. any info would be awesome, thanks!

Members with under 30 posts will be subject to a ONE DAY ban.
2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.
3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.
4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.

You may have a bad ecu. I had the same problem, was throwing an o2 sensor code, bought a new o2 sensor, put it in, reset my ecu, started my car, check engine light came back on.
My light would come on almost immediately after starting my car, I read in a manual that the o2 sensor doesn't even send a signal to the ecu until it reaches a certain temp, don't remember what that is right off hand, it was over 1,000 degrees or something crazy.
I'd say, swap ecu's and see if that solves the problem

The ECU is not likely the case. A bad ECU would give a solid CEL.
It's entirely possible that the o2 sensor just isn't right. The ONLY brands that are guaranteed to work properly are NGK/NTK or Denso. Bosch sensors are known to work improperly straight out of the box. Bosch invented the o2 sensor, so chances are most other brands are copies of that design.

In that case, do what was mentioned above and check all wiring to make sure connections are correct.
Also, did you reset the ECU afterward? It could just be throwing the old code because you never reset it.2013 Ice Cream Cruise!
