Catalytic converter delete sensor

This method also requires you to be having a working oxygen sensor. The catalytic codes usually come from the downstream sensor located closer to the tailpipe and monitor how the converter works. Follow these steps to install a defouler and make the oxygen sensor think that the converter works properly, thereby clearing the error code.

Replacing a catalytic converter is very expensive because of the filtering metal it contains. If your catalytic converter is not severely clogged or containing broken parts, you can get away with cleaning it. Cleaning the converter involves relatively affordable cleaning products and cuts down on labor costs as you can easily do it yourself.

To ensure this method will work, tap the converter with a mallet or wrench. Hit it hard enough to rattle it, but not so hard that you dent or break it.

If you hear rattling on the inside, you may have broken components or heavy sediments, which you can only fix by replacing the converter. If the catalytic converter code is still showing, there is another way to deep clean the converter by removing it.

Removing the catalytic converter or driving with a damaged one will trigger a fault code which will cause the check engine light on the dashboard to turn on and start flashing. The check engine light will flash after removing the catalytic converter because, without the catalytic converter, the downstream oxygen sensor on the exhaust pipe will detect unfiltered air, making the computer think the catalytic converter is faulty.

Typically, replacing your catalytic converter should clear the check engine light if it is well installed. Make sure the new catalytic converter meets the EPA requirements. It is best to get a new converter from the same make and model as the original one compared to a used one that will be cheaper but less efficient after a short while.

If your new catalytic converter meets state standards, but the warning light persists, you could be dealing with another problem affecting the oxygen sensor. The threads on your spark plugs match the threads on your oxygen sensors, thus the sensor will be able to thread into the back of the defouler. Buy 2. Measure the diameter of the tip portion of the oxygen sensor that extends past the threads. Select a drill bit that is slightly larger than this diameter, but still smaller than the defouler threads.

Put the defouler in a vise, and drill it out until you have removed enough material to allow the sensor to screw all the way into the defouler.

Be careful not to drill through the end of the defouler, as you do not want to increase the size of the small hole in the end of the defouler. Now, thread the drilled out defouler into the exhaust pipe where the oxygen sensor was removed from.

And are your O2 sensors directly in your cats? Where is "your area"? Unless the available fuel is leaded, it will not degrade the catalyst. Add a comment. Active Oldest Votes. Improve this answer. I have been told the same by a bunch of other people. Thank-you for the reply. That or modify flash the obd2 software to ignore the cat monitor. I believe the term that eluded you is a 'non-fouler' mounting bracket, which is basically a spacer that threads in between the existing secondary o2 sensor, and existing secondary o2 sensor hole.

It serves to remove the sensor from the flow of exhaust air such that only a little exhaust gas reaches the sensor, fooling it into thinking the cat is still removing the necessary gasses.

Is it a good idea? To address the literal question in the title, no. Just because one can doesn't mean one should. Not for the environment The cats are there to scrub out the most of the CO and NOx nastiness that is the byproduct of internal combustion. Zaid Zaid Moab I've not experienced it myself but have read forum posts of others who decat and then complain about an unbearable stench in the cabin, even with the windows rolled up.

I do agree with you that maybe a bad gasket isn't the right source for such a leak; I'll update my answer to reflect it — Zaid. Most Forum posts should be taken with a grain of salt, except for this site I have done it on hundreds of vehicles without issue. Fixin to do it on my 89 accord There is just no way fumes will get into the without the windows being rolled down. The cat will be replaced with welded on piping, so the only outlet is going to be the tailpipe.

As for the environment, yes, the cat does remove the gases which contribute to acid rain. However, the fuel in my area has impurities in it which commonly cause catalytic converters to malfunction after as little as 30, Km.

It would be too expensive to replace it on such a regular basis. There is the concern that the fumes from your exhaust could reach the vehicle cabin too. It may do more than induce a headache.

It could create life-threatening situations in some circumstances. You will create more noise when you drive. Although the sound of an engine which is not held back by a catalytic converter sounds healthy, it can also become unhealthy from a noise perspective. If you have the windows down and the engine full, you might exceed decibels without this device. Any noise above 85 decibels is potentially dangerous to your hearing health.

See above. You may use more fuel without a catalytic converter. The catalytic converter does more than convert harmful gas into something less dangerous. It also squeezes a better fuel economy out of some vehicles. However, some people have reported that once they remove this device, they discover that their miles or kilometers per gallon actually go down.

The most common explanation seems to be that they are burning more gas because their O2 sensors are not reading correctly and therefore requiring more fuel usage. Relatedly, there are reports that a notable amount of backpressure is lost. If your vehicle must go through an emissions test, then it is essential to remember that there is a visual test in addition to the performance evaluate.

Testers are usually required by law to report failures like this, which means an uncomfortable conversation will be waiting for you when you try to drive away. A failure may cause your vehicle to be impounded too. You will lose your low-end torque without a catalytic converter.

The catalytic converters in the past were very restrictive because the exhaust coming from the combustion process was extremely toxic.
