Hey need some help today my speedo just decided to stop working and then the power steering stops working about 5 min into driving, i think the speedo has something to do with the power steering not working (not adjusting pump to speed). my question is how does the speedo work is it an electronic sender or is there a cable and if so where is it. Any help is greatly appreciated. Thanx

Tried that, i bashed the shit out of it thought the needle might be sticky but there is definitely some other problem.

Do you have any aftermarket units connected to the ECU, such as Apexi RSM, AVCR, SAFC?

Well if you do, check around the ecu if any wires are grounding itself against the chasis. Well this happened to me causing the power steering to go heavy on certain corners.

Nah the ecu hasnt been touched its pretty much stock

Most probably your speedo cable has snapped, which thinks your car isnt moving therefore power steering not working. the cable is located behind your speedo cluster which then feeds through the firewall into the gearbox. new 1 only cost arnd $100 from nissan

I have been researching it extensively and the r33 has electronic speed sensor as opposed to the r32s cable driven speedo, seems that i am lookin at a problem with the speed sensor or dash cluster. Anyone have a spare dash they wanna let me borrow? I will replace the sensor and go form there.

Hmmm maybe you could use the R33 Service Manual to help diagnose the problem or to test the speed sensor. I doubt the instrument cluster would die out so fast or at all....

I got the speed sensor out doesnt physically look broken the two wires coming out of it are open circuit, unsure if that is the way they are supposed to be. I would guess it is just a permanent magnet volage generator and as the speed increases the voltage does too. If so then the wires should be connected. Anyway im gonna replace it when i find another one (so far impossible) and see if that fixes it.

Your rear hicas has been removed. The front still works off the hicas system. Light steering at low speeds heavy steering at high speeds. Default must be heavy(when you speedo stops working).

Didnt really know there was hicas at the front just thought that the power steering was adjusted according to speed. May be a good thing its default is heavy steering, especially if you are travelling quickly, dont want a slight movement of the wheel turning into a 45 degree turn.

Hey guys i have recently had the same problem in my r32. Thought i would search first and found this thread.

My speedo stopped working first, then 30mins later steering went heavy. Power fc isnt getting reading either. Guess thats cos it reads it from the speedo cable which leads me to think that the cables the problem. Also i have an rb25det gearbox. Do the r33's have a sensor in the gearbox that converts in to electrical signal or is it a cable to the dash like r32.

Also i spun the gear in the back of the dash with my fingers and the power fc picked up 20km/h but the stock speedo guage didnt so would this mean that the cable is snapped somewhere or that there is a problem with the gearing inside my dash cluster??

Power steering is now intermittant too. 1 min its working fine then the next, it goes heavy.

Hope that all makes sense. Any help would be greatly appreciated.

Cheers

33 uses an electronic sender, however you would have a mech. sender in the 33 box to make your dash work.

i'm not sure how the cable setup works (i'm just about to put a mech sender in the 25det box in my 31) but can you spin the cable at the dash end? if so i'd imagine the cable has snapped, if not then your dash would likely be the issue.

Just worked it out after a bit of searching. I didnt know why the little spastic thing wasnt spinning but the cable was. Has a slit down the side and so doesnt grip properly. Also wasnt aware that they were supposed to be 1 piece lol. So super glue it back on for now otherwise have to pay 100 for new one and install it.

Good luck with the conversion.

      Oil pan for RB25DET NEO Stagea "version"

      By Dose Pipe Sutututu · Posted

      If you have a RB25DET NEO AWD motor, you will need this: https://www.hioctanedirect.com/ASR-RB26-RWD-Street-Comp-6.5L-Sump-Suit-R32/33/34-and-VL It is made for the AWD motor, but makes it fit a RWD setup and gives you a new pickup. Just one thing, the pickup sits quite forward, compared to a conventional RB25DET RWD motor. This may or may not have contributed to my previous AWD -> RWD shitting the bed at the track.

      My car is also flex tuned. It's worth mentioning it (the LS1 ECU) has a 1D table for E85 addition and just uses the ethanol stoich part as the second point of reference. It also as a 3D timing map for Ethanol adjustment. You would think this isn't enough but it works pretty damn well. That said, I wouldn't want it in turbo application. It's like lifting non-natty, or taking meth. It gets you unrealistic results that break down more things going forward. If people used it to make the same amount of power they do on 98 then it'd be one thing. But people use it, crank it up to eleventy million PSI, it doesn't knock - but it pushes the point of failure to another, more expensive thing to break. Every time I see someone make 280kw on 98 and 350kw on E85 on the same equipment I just cry a bit and really wish they would just stay on 98 in that exact scenario. It's bad for you.

      Factory oil temp sensor in a RS4V without gauges?

      By Chi-Town · Posted

      This is kind of what I was thinking but the temp sender wire and the two pressure switch wires run through the starter subharnes and I eliminated the two pressure switch wires completely.  @GTSBoy I have a can gauge with unusually bright warnings should the oil pressure fall so the factory light isn't needed. I need to dig out my wiring diagram and see if I can sort this out.

      It's a valid point. And it is doable with the Nistune. But I'm not inclined to flex it the way Nistune does - certainly not on a Neo ECU. They're already pernickety enough to tune just one one fuel. And of course, I'm not that interested in putting in a Link or similar, on a daily. With the stock ECU, stock looking turbo, etc etc, I still stand a chance of surviving a run-in with the plod. Last time it went over the pits (which was for the transplant, for because of a run-in with the plod), the Nistuned ECU did not even raise an eyebrow. They want to see a stock ECU running the engine, and they are happy to see it do so without the check engine light** on. Never mind that the Nistune is necessary to make the stock ECU work in a different chassis without ABS, TCS, etc. **And they actually provoke the CEL to come on by disconnecting the AFM, to prove that the globe hasn't been pulled!
