Hi ho Hi ho....its off to Willal I go...

Jumped in my car yesterday after having driven it 1/2 an hour earlier with no hint of what was to come.

Started it, shift to reverse, dash lights up like a Christmas tree with faults and throttle input does nothing...car wont move.

AWD system fault light is on (see top right below) along with check engine light.

Plugged in my Access Port and found code P0847

Had a look at the GTR service manual...code is the following...

Shit....doesn't sound good

Called Martin at Willall....common problem, factory pressure sensors shit themselves. There are 3 in the transmission and are not accessible.

Needs trans/diff removal and transmission disassembly to repair. I have my suspicions that the sensor is actually OK and the pressure is in fact low from a blown seal.

What pisses me off is that this failure has nothing to do with any mods to the car...it happens to bone stock R35s. If my car was stock I could take it to Nissan and they would replace the complete transmission under warranty.

So, car is being shipped to Willal on Friday...while the trans is out will do some bullet proofing mods.

All going well Im hoping to travel from Adelaide to Melbourne Saturday 2nd Feb, stay the night and have some runs at Heathcote drags on the Sunday (there are a few R35s going for runs). Heathcote allows sub 11 sec passes with no cage...will be good to have a play with different levels of the launch control and better my single pass 10.62 at WSID

This is the first and only fault I have had with the car in 2.5 years and I have absolutely flogged the arse out of this thing....cant complain

Pretty standard failure. Talking to a few of the boys who do some work here on the West coast, they all seem to do it between 25,000-40,000kms. Sounds like you got to the very limit of age / kms before they let go.

'South Side Performance' now do complete plug-and-play sensors for the R35 as it's such a common problem.

They're only $200. Your biggest expense will be labour:

hope you can make it to Heathcote Kev

seeing what you can run with mod'd turbos vs my full bolt on stock turbo same day same track will be a great comparison for everyone (including myself) who is on the fence whether to take that next step

great opportunity to upgrade the trans - im still on the fence whether to do this as preventative or wait till something goes wrong

Speedah did you try the Warranty path with Nissan???

Also another thing, what did the 2011 front end conversion set you back??? I'm considering doing this myself with my 2010

Yes, I talked to someone at Macarther Nissan who was very helpful...told him the full story. He explained the proceedure they have to go through to gain approval (from Japan I assume). Short story is the car would be there for a week or two while they diagnose/wait for a decision then I would be charged $600/$700 to then to say they can't help me.

Im not too worried...I would rather put parts in it that dont fail. I was very fortunate that it happned inside my workshop. A week ago I was driving in the Sydney City centre during peak hour...I dont know WTF I would have done if it decided to pack it in there.

Ill be there...try and round up as many R35s as you can.

Stock wheels back on for Willal trip no. 2

Ready to go. (car has now been delivered to Willal)

If you need to transport your car from Wollongong/Sydney area interstate by someone that actually cares Mick is the man. Some of you may be familiar with his 7.4sec Torana MV454

I seriously hate transport companies all together. While I didn't have issues with CEVA, I had a fuel contamination issue a few weeks back and the GTR had to be tray back transported to Moorooka Nissan for draining. I made sure I taped up the front lip (2 layers) just in case it was scratched. Sure enough, the tape was fully scuffed when I picked it up from Nissan the next day. Luckily there was no damage.

The transport used was the GTR Roadside Assist preferred - Wilson Transport - in Brisbane. I do not recommend them, nor will ever use them again!

Have they fixed this pressure sensor problem in the later model R35's?

Nup. Transmissions are almost identical in that regard all the way to 2013. With all GT-R's its not a matter of if it will happen, its more like, when it will happen :P

    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
