Hello everyone,
So I now have P0420, catalyst system efficiency below threshold. My code reader can read live data and my O2 sensors are reading just fine during operation. I am not noticing any negative effects while driving. How do you test a catalytic converter? Anyone else had this code and know an easy way to troubleshoot? Is this common with manifold leaks? Check for a random hole in the exhaust?
Thanks
