What are the o2 Sensors on late model camaros considered? 1, 2, 3 or 4 wire?

 

LS1's have 4-wire sensors. Heater power, heater ground, signal wire, and signal ground.

 

Ok, here is my other question...

I have hooked up a LC-1 in place of the b2s1 o2 sensor and wired it to do both my wb and nb. I hooked up the analog output 1 (yeller wire) to the pcm at pin #66 (purple wire) which I thought was the high side for that o2 sensor. I am only reading around 447-451mv on my scanner for b2s1. Do I need to configure output 1 on my lc-1 or should it stay at the default setting.

 

I had the same problem every time I tried to get my LC1 to work as a NBO2. If you look at my diagram (and based on what some have said), I believe you need to have the low wire grounded. I never got to figuring out if that was my problem or not as I sold my LC1 for an LM1.

 

I've got a PLX, and I was told I needed to ground the low side of the heater circuit. I did so when I installed mine and it works great, going through the EGR.

 

I've got my wb going through my egr (pin #55) and my nb through my high side b2s1 (pin #66) Should I just plug the stock nb back up and zip tie the sensor up out of the way to ground the low side? will this work?

 

I don't think so, it's been a while since I did mine, but I believe that the narrowband grounds through the connection to the exhaust. In other words, if it isn't screwed in, it isn't grounded.

 

You right...I tried it this weekend and no luck...guess I will ground it to the frame/block or etc...
