Re:


Had my X-Trail for exactly a year before I found time to sort it (I was a mechanic in a former life and look after my own cars)
It's a 2005 T30 Ti Auto, much nicer than the diesel manual I had in UK
Doing the idle relearn etc. (using help from this forum) did nothing so I replaced the cam and crank sensors (bought as a pair in a "genuine Nissan" box) last night.
Both of the sensors that came out were totally black plastic with some kind of "channels" embossed in them.
The replacements were both metal tipped (bit like a battery case I suppose)
I reset the ECU (disconnected the battery) then did the idle relearn etc using a clock and got the engine warning light flashing first go
That did the trick and it now idles at about 750 rpm
I'm a happy bunny now - thank you.
Getting at the crank sensor was almost impossible until I hit on the idea of removing the metal bracket that support the inlet manifold near the cam sensor (four bolts) after which it was relatively easy(ish)

Re:


Hi everyone
I am new to the forum and this is my first post and i hope its on the right spot emoticon
I have a japanese made T30 aut. 2.0 QR20DE 4x4 year 2000/2001 I guess its one of the first xtrails on the japanese market. Nowadays it has [sign in to see URL]
i have some issues with air intake. The car has accelerator problems. It has no power when I ask for it.
I get codes like P0110/P0121/P0120/P1122/P1320 I think these codes are mostly related together. I just cleaned Maf sensor that seemed to help for now. (I am thinking of getting a new one) I checked the cables for accelerator pedal and Tps with only keys on and off and they all look Ok.

First question:
I also have high idle around 1300rpm. I tried to to pedal dance for Idle Air Relearn but whenever I start the car after the mil stops blinking I have no Accelerator pedal. It does absolutely nothing until i turn the car off and a new start everything seems ok but my rpm never comes down. Am I missing something???

Another question: I think this car has Obd1 because japan started obd2 protocol in 2003. So is there a way to connect it to something(other than consult because I have no place nearby that has consult) to read live data or the codes????

Another question: Since it is an imported car I can not get any spare parts where I am easily. Any web site you can recommend to buy sensors at least????

I know its lots of unrelated questions but I live in Patagonia and everything is very very far away emoticon
Thanks a lot for your thoughts/reply/help
Cheers from Patagonia
Cem

Re:


I had this issue appear at 240,000km on my 04 ti exxy. I ignored it as fuel economy was not effected and engine was still idling smooth. It just revved itself every few seconds. Interesting to read it was the cam/crank sensors as I replaced them at 130,000 give or take so it seems it may have been them a second time after similar km. Another tip if your exxy its getting this old is to do front wheel bearings at around the same km. Had to do mine twice both times around 130,000km apart and both times the drivers side front bearing. Other than this it has been a faultless car up till now at 300,000 when the head gasket has gone. CD player is no exjecting disks and every now and then the cruise turns itself on and off which fixes itself after a few days.

I got another 50,000km after the engine was flaring / rev ing itself so don't stress if u get the fault on a trip.

Tried idle relearn and it did not help. Replaced the sensors myself for $70 and as the poster a few posts up wrote it's easy enough if u remove the bracket to give extra room and pull out the air cleaner lid and arm anyone Good with tools can do it.

Re: FLARING AT IDLE 1700-2500 RPM.


Guys,

I had this issue recently with my S5 T31 2012 Exy.

After trying to reset the Idle using all the tips in the forum I had no success.

At my regular service interval my mechanic cleaned out the throttle body and the flaring is gone.
I also had issues with the revs when the aircon was on and that has also been fixed.

My mechanic said that any kind of dirt or soot in the throttle body can play havoc with sensors and the like.

This may save someone time.

cheers,
Tom

Re: 'hunting' idle


I hope this is related, but until I find a 2011-2013 T31 TL auto diesel to buy, I thought I'd buy a cheap T30 for now. I went to look at one on the weekend, and after it was warmed up, it started revving high and sorta "hunting" by dropping the revs, then revving high again. Bit like 'cutting out' to lower the revs every 15 seconds, but consistently revving 1700-2000rpm.

Now here's where it gets interesting....

It only did it in Park & Neutral...and when hot...which is why the owner never discovered it. (Who leaves their car idling in Park or Neutral when hot? You park the car and turn it off.)

So in Drive, Reverse, or any gear, it idles normally @900rpm. The issue is only present when hot, in Park or Neutral! Driving the vehicle showed no signs of anything abnormal, as long as you have it in Drive, or Reverse. I suspect if you flipped it into Neutral when stopped at the lights the issue would show, but then who does that often either?

At first I suspected a temperature sensor, but after reading all of this, I can't help think that if it doesn't do it in Drive or Reverse when the engine is under load, it has to be ECU/electrical/Idle settings?

I've suggested he try the idle re-learn procedure, or take it back to the mechanic that last worked on it.

I found out the car had recently had the exhaust manifold replaced on it due to the original cracking. I worry that if the manifold came complete with CAT and O2 sensor, then even though the CAT recall was done, the used part they installed might NOT be the 'recall' part, but an old one that missed the recall. But either way, if the ECU had 'learnt' an idle setting with a cracked manifold that is no longer present, wouldn't it also re-learn with the fixed one?

In my 'other' world we call this "adaption tables", and we reset the adaption tables every time we do any significant work, like valve clearances, new air filters, replacing O2 sensors, etc.

Hi Wiz,

Yes, doing the idle relearn would certainly be the first thing to do. This would also need the pedal released relearn to be done first with the Xtrail warmed up with aircon and lights off (no extra load).

Then re-evaluate the condition.

Hi Wiz, I have recently had this issue that is not fixed. I had my 05 TI services by my local mechanic and now I noticed that the idle flares between 1500 to 2000 when in park. It also seems the auto transmission seem to bump a little if you take your foot off the accelerator as well. I took it back to the mechanic and he is unsure why. He did clean the throttle body and replaced the plugs which he said were pinging badly. I wonder if this means the idle had fixed in a poorly tuned state. None of these issues was apparent before the service. Should I get the idle reset as a matter of course?

What exactly is a pedal release relearn?
