Refeigerant pressure sensor - function not avalible.

Postby r34gtt » Sun Nov 11, 2018 4:16 pm

Hi all,
I have an rb25det R34 Gtt
In the ecu Pinout pin 57 is labled as : Refrigerant pressure sensor signal * function not avalible.
How does the a/c system function without this? Does it just assume the pressure is ok?

Doing a wire tuck on my r34 running platinum pro, the pressure sensor has 3 wires; ground, senspr power supply and refrigerant pressure sensor signal *.
If the platinum pro does not support this then i can delete the plug all together?

I believe it is shared to the OEM ECU but not needed to control the A/C with the Pro. Just so long as something is handling the over-pressure to cut the request signal to the ECU.

So i ended up following the refrigerant pressure signal wire back to the Ecu only (Pin57) , which means there is no over/under pressure cutout now?
