Does anyone know the signal range for an RB26 oil pressure sensor? 0-5V?

I want to switch the stock oil pressure sensor with something more accurate and reliable that sends the same signal voltage. i replaced my stock sensor with a genuine Nissan sensor, but i think my Nitto oil pump killed it already. I eventually want to put a Haltech in my BNR32. i can buy a haltech sensor and run the stock pressure sensor for the gauge but i would like to find a same voltage range sensor that would give an accurate reading for both the haltech and the factory gauge.

The standard sensor is 0-5v but I've never seen the calibration for it to confirm if its the same as the generic one Haltech uses....most likely it is the same or sufficiently similar (considering you don't exactly get an exact reading from the stock gauge.....)

In any case your oil pump doesn't damage your pressure sender.....time and 000s of klm of vibration do. They are a reasonably common failure, just replace the standard one....in your case I'd go second hand if you intend to go aftermarket ECU soon anyway

So i wired the AUX 0-5v output from my AEM 0-150 oil pressure gauge to the factory oil pressure pigtail. The gauge didnt show any signs of life but now my climate control display is looking pretty screwed. Not sure if its coincidence or not.

First thing i did when i bought the car was replace the bad oil pressure sensor. Oil pressure was strong after that. But after i rebuilt the engine that new sensor worked fine for a while then quickly started showing low or no pressure. Worried, i replaced it with the AEM and oil pressure was 90+psi cold at idle. I dont want aftermarket gauges in the car so i was hoping for an alternative to the stock sensor that would allow the stock gauge to function accurately.

Sorry am I missing something here or are u trying to read pressure off your temp gauge. I am a bit confused.

I would like to read oil pressure from the stock gauge but looking for a more accurate sensor. After a couple days the heater controls started working normal again.

Correct me if I am wrong but I thought the stock oil pressure SWITCH is just a single wire 5v switch. I don't know what they are calibrated to read between in terms if their range 0-100psi ? 0-150 psi ?

If you're installing a 3 pin pressure SENSOR then the ecu needs to be calibrated to read the range correctly otherwise it won't know what to display. If you're still running a stock ECU then how are you going to calibrate the sensor correctly?

    • Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”
    • Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2  
    • Thank you so much for the help
    • Yes it is ATF. I quote @Duncan "it takes a good synthentic auto trans fluid like Castrol Transmax Z" It's not a diff. It's a transfer case. Totally different thing. Yes, fluid will come out the sender hole. No you do not really need to drain it. Just pull the old, quickly poke the new, clean up and top up. But realistically, you should probably take the opportunity to change it anyway.
    • Hey all. I’m looking on replacing my speed sensor on my R33 GTR. Will the center differential need to be drained, and if so, the center diff uses ATF fluid D? I found information on the transmission, front diff and rear diff. Can’t find a for sure answer for the center diff. Any help will be greatly appreciated.
