I was doing some donuts tonight (well as best as my 4wd NA skyline does lol) and then I drove off and noticed the steering was really heavy.

I pulled over and checked the power steering pump which seemed to be working fine and didn't look like it had lost any fluid.

It took a 3-point turn in a wide street to turn around (cause I didnt wanna go through the roundabout ahead incase I couldn't turn enough).

I got the car home but the steering wheel takes heaps more effort to turn and doesn't seem to want to turn very far (only just made the turn into my driveway). I'll have another look now but just thought I'd see if someone knew what it would be, if it's just the power steering isn't working or if it's something more severe.

Thanks in advance.

I just had a look under the bonnet with the engine on and the power steering fluid in the resorvoir is just sitting there and not being pumped around like it usually does??

All the belts are running fine etc and I couldn't hear any abnormal noises.

I've had a bit of a look around the front wheels, under the car and under the bonnet but cant see anything out of the ordinary?

What should I check/look for?

Can anyone help me? I'm guessing I've probably stuffed my P/S pump from holding it on full-lock too long. They don't like that do they?

I'll get my mate to have a look at it when he finishes work cause he just replaced the one in his WRX but I was hoping someone could tell me some things to check now.

The P/S fluid is full and no sign of leaks, hoses all seem fine (well the ones I can see), P/S belt seems to be running fine, no noises but the fluid in the P/S resorvoir is just sitting still and not being pumped around like you can usually see.

Does that sound like it would just be the pump not working?

The steering is REALLY heavy and hard to turn.

I had a look at the TPS and it looked fine, but what connections should I be looking at exactly? How does TPS affect power steering not working? Skylines have variable P/S assist don't they, but doesn't the P/S constantly get pumped around (ie you can see it moving in PS resorvoir) regardless of throttle input? Wouldn't the variable P/S be controlled by a speed input anyway?

Also I just ran the car for a bit to make sure the power steering still wasn't working and had a look under the car for P/S leaks and noticed fluid leaking from the exhaust flanges? I got a cat-back exhaust put on recently and it's leaking from the new flange joins. Is my car running rich or is it just water? I imagine if fluid is leaking then so are exhaust gases? It's not leaking heaps just a slow drip.

Could any of these problems be related? Like if the TPS is causing the P/S problem I imagine it could be causing over-fuelling and hence the fluid leaking from the exhaust?

Please forgive my noobness with car problems.

Any help would be GREATLY appreciated!

Maybe the HICAS?

My steering is very heavy too... Its been like this since i got the car..

Someone said there is a HICAS mode which turns the steering to hwy mode when going fast and normal when going slow? Could be your problem?

I need to find out more too

I just realised my speedo isn't working. Do you think that could be the reason for the loss of power steering? If it is variable with speed perhaps it offers no power assistance if the speedo is constantly reading 0km/h?

the hicas requires a speed input to work properly, as it hardens up at higher speeds (in r33s anyway)

so the hicas does not know how fast you are going, or any other problems, it usually goes into its high speed mode which makes the steering heavy even at lower speeds.

yeh i agree with siksII,

the speedo not working maybe causing the hicas to stay in high speed mode, and hence making ur steering heavy all the time.... have a look at the speedo, fix that and see how the steering goes.

thanks for the replies guys.

nah apparently my car doesn't have HICAS.

I had someone on here tell me 'when the speedo stops the power steering stops' so I've taken the instrument cluster out but couldn't fix it myself so I took it to my mechanic this morning and he's sending it up the coast to get fixed.

I took the car for a drive down my street, I saw the speedo get up to 20km/h (but doesn't register anything at slow speeds) but i'm not sure if steering was still heavy as I didn't try turning when it was giving a reading.

Either way, I couldn't drive around with a broken speedo anyway.

Hopefully it fixes the power steering problem but..

ToF makes a good point "your steering wheel was always easy to turn while stationary when it worked."

Also I remember looking under my bonnet and the power steering fluid in the resorvoir was being moved around and now you look at it and it just sits there.

If it is the power steering pump, would you guys suggest reco, another used one or new? And what would be some ballpark figures for each?

thanks heaps.

Fellars. I know what the problem is!!!!!

yipeee. hehehe.

In all seriousness, when I was mucking around iwth my cluster, my speedo unit in the cluster wasn't connected properly. My speedo didn't show speed and the hicas light would come on and power steerin would be lost.

Most likely what happened, is when you were chucking it, maybe the speedo came loose? It's not as silly as it seems. Once I was doing donuts and the interior light cover fell off..

I had a p/s problem in my R32, the assistance would cut out at the most inconvenient times (e.g. half-way thru a corner), turned out to be related to my electrics.

My voltage was sagging due to a dodgy earth lead from the battery, and it seems the p/s solenoid was the first component to play up, must have a narrow operating voltage range.

Can someone please put up the power steering section of the R33 workshop manual?

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
