I got a brand new sensor (o2) for my front turbo or front oxygen sensor for my rb26. But after I pluged it in my d jectro power fc went to 5.12v on that channel, and the rear one was at 0.04v. After a while of idling the rear one warms up and starts to move up slowly, but the front one isn't moving at all.

Attached is the photo of the sensor I got brand new. And I'm lost as to why this is happening, all I can think of is there has to be two kinds of sensors for a gtr r32 rb26 motor. High to low or low to high voltage. Im just guessing here.

I would appreciate any help.

maybe incorrect setting on PFC perhaps

r32 titania & r33 zirconia, there's an option in r32/33 pfc to set which one is being used (o2 sensor reg), this needs to be on for R32 and off(+ sign) for R33 gtr

edit - explained

02 REG is needed for BNR32 owners
as the PFC unit for BNR32 and BCNR33 is the same unit but the BNR32 has titania 02 sensors and BCNR33 has normal 02 sensors.
the BNR32 needs to be set as registered to make them work as titania sensors properly. Otherwise with it off the PFC assumes they are BCNR33 style 02 sensors.
This is covered in the FAQ

apexi's official answer;
There is a difference in the O2 sensor for these vehicles. (With or without internal register)
After tuning, please check () "O2 SENSOR REGISTER" for BNR32, and NOT for BCNR33.
* It may be different if the O2 sensor is modified and/or changed.

Wow. Im lost now. Where do I find the with or without internal register feature. ???

I will look over the FAQ section and see if I find anything.

Whats a titania o2 sensor??.

And whats the right part numbers for a sensor of that type.?? If you have it. I think im running normal sensors right now. The voltage starts about 0.04 and as the car runs they go up slowly.

Can someone expain this in layman's term. Lol

    • For sure the later RB26 variants had a different setup (6 cam voltage sender?), but the RB25DE/DET share the same ECU pinout/PCB footprint, and at the ECU plug it ends up being 'throttle sensor in' & 'throttle sensor out' (to A/T TCU) ...you stick a multimeter on these pins and you'll find them directly connected (0 ohms) ; I had an pair of Nissan ECUs on the bench long ago, and I noticed this throttle sensor in/out link, actually linked to an op-amp ...which was unpopulated on the NA board, but present on the T board and I went 'ah-ha!' in some moment of clarity... ...it wouldn't surprise me if they changed strategy here though (in the software and actual monitoring of this signal), because they did with other stuff (A/T signals).. and 0.45v as a trigger point makes sense, as that's what the external TCU units expect at idle ; kudos, thanks for that insight...I suppose it boils down to whether or not Consult can display real time data of that signal's voltage... ...in any event, it presents the same target...ie; rotate TPS unit to achieve 0.45v to suit both ECU&TCU, and where do you goto from there? Just disconnect TPSwitch connector and/or that plus TPSensor connector....or do you go for the throat and disconnect IACV solenoid and see if it still stalls? (probably throws a recoverable fault code and goes for default idle strategy?)...
    • I’m also conscious that e85 is slowly being phased out. Not all United’s have them anymore. Can’t take the risk of being low on petrol and assuming the servo will have it. 
    • MR HAMMER has said his piece. Painted up to avoid Rusty Rusty. Actually lines up well. (i.e it lines up the same as the unmolested GTR guard). Turns out the GTR Strut brace does foul on the bonnet vents ever so slightly. May need a little bendy bendy if intended to keep using with a strut brace. So spacing it out to clear the FAST102 is not an option. Annoyingly, the bonnet vents also foul on the heater lines running over the engine. Given this engine does not EVER require a heater, a delete loop is going to be used. Don't worry, the defogger uses the AC. The heater is basically "Do not use the aircon and turn the fan on". It will still be effective, I promise.... once I get the system regassed... Will have to revisit with unvented bonnet I suppose, and suitable strut brace. There's plans to do this and other things tonight and bleed brakes (there was a weep) and put the bumper back on, and take Good Friday morning - Because troubleshooting on the side of the road limping it home at midnight tonight is ... not very smart.
    • Thank you all for you assistance. I contacted Nistune regarding the support for the RB20DE along with my ECU Code (23710-10U00). They do have a map for it and added the RB20DE as a purchasable option now as well. They also added Malta as a Billing and Delivery options as this was missing. I was honestly amazed at their quick response and action, it took less than 24 hours. I also looked again at direct fit options for injectors, just in case I were to replace them. DeatschWerks seem to use a Bosch EV14 base and makes ones that fit mine at 440cc lowest, but also have 550cc at the same price. I tried looking for other direct fit options and managed to find one (also Bosch EV14 based) which includes a plug and play adapter on ebay. Did a small test with a Noid Light on the troubled injectors and all seems good, so they are pulsing properly electrically. One weird part is that they are missing on the same two cylinders as before I got the injectors cleaned. Mechanic also found this weird as he did not label the injectors and it is unlikely to have the faulty injectors be installed in the same cylinders.
