About The Sensor Sticking Into My Cat

[gts-4 dreamer]

The information I have found on this sensor is pretty in-conclusive. Could someone set me straight on this ?

IS this a exhuast temperature sensor ?

What is its purpose in the miriad of processes involved in running the beasty 2.5lt donk ?

This question may be redundant but would it matter if I was to simply leave this sensor out ? I assume not perceptibly since i found A pair of posts stateing that they hadnt nticed anything but this isnt quite the fact i was looking for. maybe over time something could go bang so I ask.

This is currently a problem for me as I have recently aquired a wide body catco 3" cat to match my 3" cat back system and only need a front+dump aka batmbl revised version. ^^

the catco cat has no port for this sensor so I need to know if thats a problem, I also need to know where would be an equally good place to install the sensor should it be a requirement that is not in the cat, I dont want to hinder flow and havent seen the sensor itself out of the cat so i dont know if its going to cause a choke point... possibly why its in the cat to begin with ?

if the cat is the best for this reason, can i just drill a hole an tap a thread in or is there some part of hte cat process I could damage doing this, assuming there is a chemical reaction going on in the cat to change gasses and prevent the toxicity shite aka the point of having a cat in the first place.

new cat... what to do ?

so pro's / con's of removing would be something helpful.

also in hte future a second hand pfc or equiv management system will eventually go in, will this sensor be of use to the tunning process or the day to day running on a non factory ecu? will they make use of it ?

links in various directions could help me...

cheers

Yeh, it's just an exhaust temperature sensor that is designed to light up a LED on your dashboard if the exhaust gets too hot, it's pretty superfluous, just remove it

I personally would not remove it but I know it is possible and doesn't adversly affect your car.

You can get a temp sensor bung welded in the cat at any muffler/exhaust shop for $40 or less.

Does nothing that will adversly affect the car by it not being there.

Just connects to a dash light.

Thanks guys.

Am I likely to get to a range of heat. in my exhuast that could cuase a problem ? Im assuming this is some sort of indicator of how hot the engine is running / burning ? oil temps probably being a lot more relevant, but what would this be providing a warning for ? if the exhuast is hot i doubt it will likely get to a point where this would cuase some issues. I dont know enough about it to judge that this is a safe risk to run unprotected, I dont believe it to be likely but what risks are involved... i might be a wet blanket but i wana be sure im taking an acceptable risk something isnt going to pop due to me removing something.

I've run all my cars (4 years) without the sensor.

When i say nothing will be affected, i mean it

The sensor is only there, if i recall correctly, to tell you if the cat is overheating due to mixtures not being right in the factory setup.

You are no longer running a factory setup, so it does not matter.

Hey guys i just stumbled onto this thread and was just about to ask the very same question. Thanks for the info guys.. it's helped me out also.

The temp warning is for the cat - the idea being, if the cat gets blocked by one means or another the temperature

on the upstream side will go way up. View it as a health-of-cat sensor. Exhaust shops use this as a means of

gauging just how blocked your cat is

If you delete it you won't do any harm as long as you're cat's not blocked.

Same here for me, 3 different cars and never had a problem not running it.

I had it in my old track car and the only time i used to see the light was when the car was warming up on idle on the dummy grid.

Yank the sucker out, put in your new unrestricting cat and enjoy
