HedgehogSandwich adi Posted May 26, 2002 Share Posted May 26, 2002 Anyone know what temp a cat sensor gets to inside the cat? I have to recreate the temp for a quick experiment with my now catless sensor. I suppose i could fit a dummy load across the terminals of the right resistance but i dont know this figure either. I figured it might be quicker to bung it in some molten lava or something. Does anyone know of any other way i can fool the sensor?

Flipfinger Posted May 26, 2002 Share Posted May 26, 2002 *Mycroft mode* I remember hearing that a catalytic converter gets up to about 500 kelvin on cold start. Which is 226.85 Celcius, by my (probably flawed) calculations. Quote Link to comment Share on other sites More sharing options...
HedgehogSandwich adi Posted May 26, 2002 Author Share Posted May 26, 2002 226 degress? hmm too high to recreate easily. The blow torch idea sounds good, unfortunately though the sensor is in situ, and i dont fancy setting fire to the car I reckon my best bet is to dummy load it. Anyone know the correct resistance for a temp sensor running max heat?? adi Quote Link to comment Share on other sites More sharing options...
THOR Racing Posted May 28, 2002 Share Posted May 28, 2002 May I ask why you want to remove the probe? You don't actually need it so either replace back into the exhaust or if the exhaust has no hole for it just tie it up out of the way and leave it connected. This is the simplest method. However you may require something else. Do you want to see what happens when the CAT sensor overheats??? Regards Pete Quote Link to comment Share on other sites More sharing options...
HedgehogSandwich adi Posted May 28, 2002 Author Share Posted May 28, 2002 I fitted a decat pipe a while back, now the temp probe is tied up under the car. Anyway, i'm getting the car running very rich on startup and smoking petrol smoke out of the back for a few seconds. It only happens when warm and can happen after a very short periods of time ater turnoff, eg filling with petrol. Im fairly certain this is the reason, and even if it isnt i can at least eliminate it from the list of culprits. Obviusly id rather test the theory before i go drilling holes and fitting adapters into my exhaust, hence my post. Doesnt happen when the angine is cold or after an overnight stand. adi Quote Link to comment Share on other sites More sharing options...
