100,000 yep!!
Yes, internal coolant consumption can damage a catalytic converter.
No, the catalytic converter is downstream from the EGR valve so it has no effect on it.
You will have to install a catalytic converter to get the light to go off.
That would depend on the type of vehicle. If it is a low emissions vehicle you have to go with the oem catalytic converter.
Catalytic converter plugged.
They can become clogged or they can burn out.
I have done the research and here are some online websites that can help you find a catalytic converter www.autopartswarehouse.com/catalytic_converters~pop.html
A catalytic converter should NEVER go bad unless something causes it such as a RICH or a LEAN condition. What is a "RICH OR A LEAN CONDITION"?
There can be a few reasons for a catalytic converter to go bad. One of the causes could be clogs. Other reasons include plugs not working right, and bad exhaust valves.
Maybe the heat shield on catalyytic converter Maybe the heat shield on catalytic converter Maybe the heat shield on catalytic converter Maybe the heat shield on catalytic converter
Not much info to go on but I'm assuming the vehicle has three 02 sensors, one after each bank of cylinders on that V6 and one after the catalytic converter. Bank 1 sensor 2 would be the 02 sensor after the catalytic converter. This B1 S2 monitors the catalytic converter activity. It could be the catalytic converter is at fault. It would be of help to know what the code # was.
A bad coil can damage a converter. If the engine is misfiring, it will cause raw fuel to get into the converter and that can cause failure.
