Import CAT

[Anonymous]

Morning everbody,
Just fitted a 2nd hand cat yestarday just to prove if mine had failed or not, anyway got to the final moments before a testrun and remembered i hadnt put the last sensor back in only to find the 2nd hand cat aint got no hole for it.. ? spoke to Toyota (i dont know why i bother) and they were confused.
Took it for a test run anyway and every thing is great ,it`s got all the power back and the exhuast sounds sweet again.
Does anyone know what the final sensor is for and how detremantal it is to the running of a uk car as i believe that this is a import cat.
Also the engine warning light came on just as i was getting home after about 30mins of driving, could this be showing the sensor malfunction ?

The 3rd O2 is to monitor the efficiency of the cat. As you have a Jap spec cat, as you point out there is no provision for the sensor. The CEL you are getting is undoubtedly because the sensor is missing. You have two options: Have a sensor boss welded to the exhaust post cat, or get an O2 conditioner that will fool the ECU into thinking it's there.

hey dude cheers for that. any ideas on locating one of these conditioners

I'm not sure where to source a conditioner over here, PPE sell them (not sure how much seperately though), see here.
The easiest and cheapest option would be the boss - go find a local exhaust specialist, and all they have to do is drill a hole in the pipe, and weld a nut on (they may have a proper boss) that will accept the sensor screwed into it - it's that simple.

Hi mate,

I checked the oher CATs I had, but both of those are also J-Specs.  I would say the easiest resolve would be to get a bung welded (keep your old CAT for that).

Where are you located again?  I have someone at Brands Hatch who can do it while you wait.  I'll cover the charge of course which should only be £10.

Just thought I'd say - now that's what I call customer service!
