Oxygen sensor wiring diagram anyone?

[Black Turbo LTZ]

Does anyone have access to tell me what each of the 4 wires of our oxygen sensor are.

What are you attempting to do?

What are you attempting to do?

I need the signal wire for my Air Fuel Gauge, got the gauge free when I bought my boost gauge from autometer so I might as well hook it up.

To be honest I wouldn't waste your time. Narrowband gauges are useless. Unless you like the pretty sweeping digital lights

 

[Black Turbo LTZ]

It was free and is already sitting beside my boost gauge so I might as well...don't wanna waste it.

Got my answer, for anyone who wants to know it the Yellow/Brown wire off the main harness to the plug into the sensor.

After all, it is very important to accurately monitor your part throttle A/F ratio while it is between the mixture ratios of 14:1 and 15:1.

You wouldn't want to lean like this guy...

Again I didn't pay for it so why let it sit ...

Did you find the complete wiring diagram for the o2?

I'm looking to install a wideband in place of our narrowband and looking for the function of all the wires.

Off hand I can't remember, I just called my service tech at my local dealer and he faxed me over the diagram

PM me next week and I'll pull it up for you. I away from my computer until Monday and I'm sure to forget

I will definitely remind you, but do you happen to know if our ecm will care if the heater for the stock o2 is missing?

I'm planning on putting in a Innovate MTX-L wideband in place of the narrowband and want to know if I'm going to need to buy a spare o2 to hack apart or set up a fake heater.

yes it will send a code.. i installed a LC1 Wideband gauge.. if you have the trifecta tune you can turn the code off so it dont come on.

Thank you very much!

I can't wait to have my wideband in.

 

[rcmn0022]

Alright if I'm reading this correctly, there is a positive signal present at pin 47 and 68 or at pins 67?

I'm thinking it must be 67 since I've got it hooked the other way and my ecm is not receiving a signal.

5290 is heater +12V
3113/5035 are heater grounds
1664/1669 are signal grounds
1665/1668 are signal inputs from the narrowband
