no o2 sensor reading on power fc!! need some help

[jrb92se]

i was checking the sensors on my pfc and realised im getting no o2 sensor reading. i havent really investigated it yet but i figure it just needs to be replaced I READ THE PART# STICKY but i couldnt find a p/n for the s2 rb25det o/2 sensor. which one should i use (oem nissan,bosch etc.) thanks guys!!

I don´t have any o2 sensor to check in my power fc commander. I have a s1 rb25det , and I think that the power fc doesn´t use the o2 sensor to make any change in the fuel map.

No. It's shown in the sensor voltages. and No, the PFC does use o2 sensor for closed loop fueling unless you turn it off.

You can use almost any 3 wire o2 sensor and wire it in. I think the z32 o2 might be plug and play.

yeah its in the sensor check screen. thanks for the help

This is funny , I was checking my o2 voltage ,and no change at all, is always at 0.02 v , so I assume that my o2 sensor is bad too......

the bosch p/n is 13091 for the oem style on the s2 rb25det. it is the same as the 92 300zx trubo upstream o2 sensor

That or your wiring is bad.
