[if you did the diagnostic in a garage or low light situation it will come up with a sensor problem. I checked my on my R33 in the dark and it told me there was a problem with that sensor, did it in daylilght and there was no problems. I don't think it woujld stop your air con from working though. Do you know if the compressor is OK?

I have had ongoing Aircon problems. It WORKS, but its only full cold 18`c, but anything >= 19`c it runs at full hot. Suspected that my dash cabin sensor was the culprit, but Have since been informed by Powerplay that I'm missing the external temp sensor up the front in the bay somewhere. Just waiting to get it fixed and gassed :P

Glad it's not just me, having the same problems with my R32, compressor didn't want to spool up, when it did it cycled on & off without cooling the car down. Diagnostic check in driveway displayed sunload sensor code, was wondering where it is & how to get to it/fix/change it. Might also get the system checked to see if it needs regasssing. Had the car for a year, no dramas up till now. Any aircon gurus out there?

Mines leaking because the origional Compressor carked it, and had a new one put it, but apparently GTR compressors dont fit the GTS-t. They FIT, but one of the connectors is too big, hence the leak. Still waiting for Powerplay to get back to me about a replacement.

Water temp sensor for a rb20det is the same as a nissan maxima v6 model... Yeah paid $60 from nissan... Fitted in 20 seconds with a bit of thread tape....

Had the same water temp sensor in the same car, Neo 32. Replaced the sensor with a part from nissan (~$70) aircon works fine now.

Sorry for reviving an old thread.
I have this exact issue for my R33 Type M GTST here in Japan. What was the fix. It's driving me insane!

    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
