If the catalytic converter is below the threshold for efficiency or if the oxygen sensor/s is faulty, there is likely to be no drivability issues. Find a catalytic converter exempted for a California vehicle that is of the same make, model, and model year as the federal vehicle, except for the engine family. ) I need to get emissions done ASAP, but my CEL just came on with a code 64 {Catalytic Converter Efficiency Failure}. It is insensitive to combustion efficiency and catalytic converter operation ('what goes in must come out'). Knowing how scrap catalytic converter prices are determined is important as well. Even if the 10 grams weren't found in the ashes, a difference of 10 grams of particulates from a 40 lb. When the values of both sensors are similar the ECU infers a low efficiency in the catalyst system. Code P0420 Definition. On the basis of the results of numerical calculations, the improvement in the performance of the catalytic converter with parabolic axial active material distribution compared with the respective uniform distribution is verified.
