Cat temp sensor..

[MaccyD]

In a bit of a mix up it seems the decat i bought has an unexpected sized hole where the cat temp sensor goes so it seems im going to have to run without one. Will it effect my fuel economy to not have it on there and if it doesnt can i do something to disable the cat temp warning light from coming on?

Any input apreciated, thanks.

i think thats the oxygen sensor and im prity sure its not good to run your car without one.your car will run like a pig because the mixture will be wrong. im not a 100% so id wait for some one with a little bit more knowledge.

the top sensor is the lambda (O2), you need that or it will run really pants.

the lower one is the cat temp sensor. and you can run without it, most decats dont have these anyway.

cheers rick, i was hoping that was the case. now i need to find a bung for the decat. and a vice to bend the bracing into the correct position.

i wasnt aware that there was two sensors

cant speak for a glanza cat, but gt's have lambda at the top and a cat temp sensor poking out very close to the bottom.

There identical

Retain the top o2 sensor, ditch the lower cat temp as Rick said.

You probably got a bung to screw into the lower sensor boss?
