I am looking a getting a new cat.

But when i looked at the one on the car i found this

post-49054-1213009579_thumb.jpg

just wondering what this is, and if i need it as the new cat does not seem to have a place to fit this sensor?

by the way it's a x force hi-flow cat i'm looking at.

it could be an exhaust gas temp sensor.. just go to your local exhaust shop and get then to weld a new nut close to it's original location once you have fitted the new cat, or you could move it to the right of the flange in the photo if you want to do it before you fit it...

its a precat heater IIRC...but i can be wrong

your cat doesnt work efficiently until its hot

that aids it in heating

take it out of your cat, and push it up above into the hole the wire comes from. if you disconnect it a light will come on on your dash

no sorry definately not a preheater for the cat on these.

it is just a cat temp sensor, it runs a light on the dash if the cat gets too hot (ie blocked). I have been running with mine disconnected for years.

+1 when i got my car i used to hit bumps and see a red light flash,took it in and got a new cat sensor,then a lil while ago i was in my local spot with my bikes and had a bit of fun in a huge open area of dirt/grass,broke the bead on 3 of my 18's and snapped the cat sensor wire clean off...lights on constantly now.ya get used to it :thumbsup:

ahh oki doki this was on a 32gtr it doesn't show an error when you disconnect it. If it does, and you don't have a bung in the cat (or no cat at all like us) just chuck it under the car somewhere it can read ambient temp

Kind of off topic.. but why the hell do people put exhauste temp gauges in?

Who cares what exhaust temp is?.. its on its way out?

i know some people use the exhaust gas temp displayed on a gauge as a rough sign of what the afr's are doing, its an old school way though.

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:

      R34 manual conversion speed signal wire finding, need help

      By GTSBoy · Posted

      Yes. Autos typically work from the speed sensor on the pinion shaft of the diff. I also think that even if you have a proper speed sensor for the bog manual in the manual box, that the signal it outputs is not compatible with the auto dash anyway. You should consult that manual (the book, not the gearbox).

      And I just realised that that advice is slightly nonsensical for a GTR, because you need 2 of them. But it is otherwise true.

      Duncan's V37.......race car?

      By Duncan · Posted

      Having had a reasonable look at the car, I'll be able to remove the (one time) rams and retract the hinge (they are held in the down location by a tiny (m3?) sacrificial screw) which will get it physically back in shape. From there if you remove the rams you need a resistor to turn off the airbag light (as Mark said, there are plug in kits and I might go that way because its reversible). And...per all the threads on here, even if you have the resistors to turn off the airbag light, the bonnet light will stay on as it writes to the airbag computer history - that is either replace the airbag controller, reprogam the EPROM (if I can work out how), or remove the globe from the dash. Having seen how sensitive this system is, if I had my time over I'd pre-emptively remove the rams, even on a road car, because this is all a very unnecessary pain in the arse. Reminds me, time to go and have a look at the Fuga too....
