Replacement Of Cat

[Pal]

Hey Guys,

at heading states, was just trying to remove the sensor from my old cat when the hex head has broken off leaving the threaded section and probe stuck in there

have traced the wiring back to under the passengers seat to a box (just by feel at the moment as will have to remove the seat to get at it)

has anyone done this and how to repair. need the car so any help quickly would be great.

It's not needed, all it does is activate a light on the dash when your cat gets too hot. Previous owner had cut the one in my 32 so I just poked the cable back up through the hole

k so just cut it, do i need to do anything to the wires, wind them together/keep separated.

[bubba]

Always a good idea when getting wires but I have a feeling it's more of a thermocouple (IIRC it was just one sheathed wire)?

[Pal]

have chopped it, there are two wires, my guess would be that when it gets to temp the two wires connect and brings the light on, so keeping separate at the moment.

will be getting a new one anyway so will leave it like that, thanks bubba

anyone know where i can get a new EGT sensor from?? had a look around the www and not much info

[bubba]

I've never seen one for sale, ever.. have you tried Northside Nissan? probably be ex-Japland with an overnight premium.

Also maybe try Steve May, he might have one on a half cut somewhere.

[gotRICE?]

Maybe put up a WTB? There must be a zillion people runnung without them

I had mine jammed under the exhaust shield for 3 years lol. Untill i unplugged it from under the seat and removed it for a wideband to use the grommet.

If i knew where mine was id fire it over to you. I tend to be a bit hap hazzard with useless parts like that though.

thanks guys,

will keep a eye out for a wrecked r33 and also ring northsides. one will pop up somewhere.

[Pal]

Anyone know the thread of the egt sensor screw?

If you're going to that much trouble why don't you buy a proper exhaust gas temperature gauge c/w thermocouple?

[Pal]

It's only a stocker daily, don't want gauges all over my dash.

Measurement for future reference is M12 by 1.25
