Oil Pressure Sensor Upgrade?

[Thomas0zero]

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

Check your wiring.........and double check your sensors cos they are probably ok. Very unlikely to get two duds in a row, they are simple and generally failsafe.

Okay, thanks guys!

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.

Automatic CECON, nice.

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.

Are you talking about the oil gauge in the photo?

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?
