VQ35DE 3.5L V6
~170K miles at time of posting.

This car has been road hard and put away wet. but it's a fun daily driver so I'm rocking it until it gives up the ghost 100%.

Wow just realized that this vehicle has dual 4.9 widebands with a square connector?!

AF-H1 – Heater control
A/F IA1 – Pumping Cell via Trim Resistor
AF-VM1 – Reference (common) 2.5V above PCM ground
AF-UN1 – Nernst Cell Voltage (450 mv when measured from AF-UN1 to AF-VM1 - also carries current for pumped reference)
AF-IP1 – Pumping Cell
Fused Circuit- Heater feed to sensor from battery

My Nissan was unfortunately made after a round of cost cuts so mine has zero of these six wire sensors

It may not be a LSU 4.9. There's a the Denso/NTK equivalent with the same mechanism of action, but different characteristic curve for pump current vs. lambda.

Is there a way to check if I would get the sensor in my hands?

Here you are all three brands PNs for same thing

I am starting to think LSU 4.2

That connector really looks like AEM 30-2001 which is LSU4.2 does not it?
