If one of the upstream sensors fails, will the ecm still trim based on the other sensor? 96 k1500.

Yes, but only if it recognizes that it has failed. If the O2 sensor sends incorrect data, it won't recognize that it's failed at all. Why do you ask?If one of the upstream sensors fails, will the ecm still trim based on the other sensor? 96 k1500.
I have no sensors connected currently. And only one hole to put a sensor (until i get my new headers) the wiring Is also damaged so trying to figure out which bank to wire into. It currently just shows codes for circuit failures as no o2 is present.Yes, but only if it recognizes that it has failed.

It'll run open loop without the O2 sensor plugged in. Not very efficient, but it'll work. Plug in the one on the bank that has the bung, and install a bung on the other.I have no sensors connected currently.

I bought a new sensor and the wiring kit to repair it. Im just trying to get it too run closed loop until i get my new headers and exhaust done. I was thinking if i wire b1s1 and leave the other two disconnected it will still trim.It'll run open loop without the O2 sensor plugged in. Not very efficient, but it'll work.

How long are you trying to run it this way? If anything is wrong in bank 2 the ECM won't be able to compensate, and it definitely won't pass inspectionI bought a new sensor and the wiring kit to repair it.

Its run with no sensors for 4 years. Very roughly. Built engine and its not happy. Ill have headers and new exhaust in a few weeks. Thats also part of the reason im trying to get the wiring sorted out now.How long are you trying to run it this way?

4 weeks isn't too long compared to 4 years lol. Yeah get the wiring fixed, and install the one, it'll still show a code, but it should run better.Its run with no sensors for 4 years. Very roughly.

Even with an O2 sensor, it may not be happy with your built engine. Depending on how modified it is you'll need a tune before it'll get happy.Built engine and its not happy.
So im trying to get the wiring sorted. after i have everything working i have a 411 waiting for swap and a buddy of mine has hp tuners. But im still having trouble just getting the o2 plugs sorted at this point. Im gonna make a seperate post about it belowEven with an O2 sensor, it may not be happy with your built engine.
