Cat Temp Sensor

[Botters]

I just recently replace my cat with a nice 3" 200cel cat. And very happy with it i might add.

My only problem now is that, i had to cut off the old Cat temp sensor cus it was that tight i couldnt get it off while under the car. Once i had the old cat off the car i was able to get the sensor off.

I screwed the temp sensor into the new cat just to fill the temp sensor hole.

Anyways the temp sensor has come loose now and fallen off somewhere in my travels.

Does anyone know the size of temp sensor so i can just get a bolt to fill the hole?

Cheers boys

Not 100% for R33, but on my R32 all it did was light a warning lamp on the dash. Wasn't actually an ECU input iirc.

Probably best to get a second opinion, but chances are it's fine to bolt the hole.

It hasnt affected the car one bit since i cut off the sensor

All i want to do is just bung up the hole cus it leaks and makes the exhaust sound a little funny.

So i just want to put a bolt in it but not sure what size a bolt to get.

if you still have the old cat take it to a bolt place and get it matched up... if your cat is stainless get a stainless bolt as zinc and stainless dont go together 2 well where heat is involved..

Likely 1/8" NPT 28 tpi, that is what the manifold ones are, and I'm pretty sure the cat ones are the same [from memory].

Don't get a 1/8" BPT they are close, but only 27 tpi.
