Lq9 O2 sensors
Lq9 O2 sensors Hello everyone, getting back on working on the nova. Just amazed in all the LS parts available now.
I need to buy O2 sensors for my nova, just dont know what to buy. Here's the specs of the car
Lq9 6.0
LS6 intake
Reworked fbody harness
Fbody ecu
Hooker blackheart headers
Thanks for your help

Sensors may have various connectors and harness lengths.
If you know the yr, and where the engine came from, I'd start there. If the harness has been replaced, take note on the type of plug, on it.

There are a few different o2 connectors. Take a picture of the connector on your wiring harness where your o2 sensor connects and post it up. I am selling some o2 sensors for cheap that I cant use anymore. I bought the sensors for my stock harness, but then I swapped in a PSI harness and the connectors were different. Less than 250 miles on them. PM if interested.

Don't forget that a vehicle originally equipped with your LQ9 had O2 sensors before and after catalytic converter: make sure you get the correct ones! I am afraid I do not remember which ones I used on my LQ9 swap...

Make sure you have the correct setup for your ECU and harness, not just the engine. I went through this on my LQ4... specifically check isolated ground vs isolated ground. I had a mismatch on mine, I think my my sensors and wiring was for isolated ground but my ECU wanted case grounds. I had to ground the return wires to make it work.
