Will a hollowed out cat throw a code?

Will a hollowed out cat throw a code?

it shouldn’t throw any codes as long as you keep the O2 sensors hooked up. if you delete the cat entirely and do not hook up the O2 sensors, you will throw codes and run rich.

Where is the O2 sensor in the catalytic converter?

This code is triggered when the engine control unit recognizes a faulty catalytic converter. It uses one O2 sensor in the front of the exhaust, and one O2 sensor in the rear of the catalytic converter to measure the efficiency of the catalytic converter.

How can I fake an O2 sensor on my car?

Install the dummy O2 sensor (also called an O2 sensor simulator) by turning it clockwise into the exhaust just as though you were installing a regular O2 sensor. Connect the electrical wiring to the dummy sensor. Lower the vehicle to the ground and start the engine.

What causes the O2 sensor to show the code po420?

Rich or lean mixtures can damage the catalytic converter, and when the catalytic converter is damaged/filled with fuel, the efficiency will be low, and the rear O2 sensor will see that and show the trigger the code Po420.

What happens if you disable the O2 sensor?

If you remove or disable your O2 sensor, you will not pass state vehicle emissions testing, as this modification is routinely used by those using their vehicles for off-road or track racing purposes. Writer Bio

What do you mean by downstream or before Cat O2 sensors?

He means the downstream or after cat o2 sensors. I have mine removed and tuned out. There are no negative side affects as these sensors only monitor the efficiency of the catalyst. Your upstream or before cat o2 sensors are what determines if you are running the proper air/fuel ratio.

Is there a cheap way to get rid of O2 sensors?

You can get a tuner to eliminate the O2 sensors, but I doubt that’s the “cheap way” you’re looking for. how much is a tuner that would get rid of them? At one time you could get whats called o2 eliminators. They plug in inplace of the post cat o2 sensors and fool the ecm into thinking the cats are still present and functioning properly.

Are there any negative side affects to using a cat sensor?

There are no negative side affects as these sensors only monitor the efficiency of the catalyst. Your upstream or before cat o2 sensors are what determines if you are running the proper air/fuel ratio. Keep in mind, cats are a federal requirement to run on the highway, but I have never had anyone ask or look at my vehicles.

What happens if I remove the exhaust sensor?

Without them the EFI goes into limp mode and fuel mileage goes out the window. He means the downstream or after cat o2 sensors. I have mine removed and tuned out. There are no negative side affects as these sensors only monitor the efficiency of the catalyst.
