I have heard that the catalyst efficiency sensor can be disabled by a simple wiring trick so that the MIL code won't be tripped.

I have installed and aftermarket catalytic converter on my 99 Accord 2.3 and my check engine light has been on since.

Does anybody have any insite on this?

Thanks,

by doing that you'll run rich or lean and you won't even know it..

 

you need to buy (or make) an o2 simulator. that'll get rid of the cel. the o2 sensor has nothing to do with running lean or rich. it lets the car know that the cat. conv. is doing it's job by cleaning the exhaust gases. i put an o2 sim. on my car to get rid of the cel. there is no real need for a 2nd o2 sensor anyhow.

 

where can I get this O2 simulator

try welding the hole closed and leaving the oxygen sensor loose under the car but secured. its all good if it gets wet and shit but your check engine light wont come on. I have straight piping on my 99 accord v6 and my check engine light has never come on.

try it out
