Catalytic Converter Sensor

[poobah]

hey , i've got an r32 gtst, and just bought an xforce 3inch cat. i tried to remove the sensor in the stock cat but coz its rusted in heaps i just rounded the bolt. any ideas on how i could get it off??

I was also thinking as a last resort to just cut it off and not run one at all, would that be a problem??

Need help.

thanks.

yeah. it is just a over temp sensor. i got rid of mine cause it was shorting out

oh awsome! so no problem with the car after? some cars have a light that comes up on the dash? to say that the cats not plugged in or sumthin.

mine was coming on saying that the cat was too hot before i had even started the car in the morning

sorry to bring up an old topic..but how do u remove the sensor? can u just cut it in half n then block up off the hole in the cat with a screw?

If you read the first post, getting the rusted thing out is the problem. Covered a lot, Its no biggy as in a R32, it doesn't connect to the ECU in any way. Simply turns the dash light on.

what about in a 33 ?? I thought they did connect to the ECU....

makes sense for the ecu to know exhuast temps... its important for tuning vehicles to have exhaust temps.....

For tuning yes, for stock, prolly not so, as zhaust temp can be derived of sorts from the O2 sensor.

I doubt strongly the sensor is of any real accuracy; and truly IS just to warn when the things too hot (blocked)

Thread revival I just found out my sensor cable coming out of the cat is snipped and I can't find the cable that goes from the car to the cat but my question mainly is in reference to its importance in tuning. I am about to have my car tuned. Should I get this sorted out beforehand?

Don't worry about it - it has no effect on the tune.
