The P0422 trouble code is a generic OBD-II trouble code. The P0422 code suggests that the catalyst efficiency is below the normal threshold in the first engine bank, which is generally the bank that houses the number one cylinder.
What causes a P0422 code?
Fault Code Definition
Code P0422 indicates that the Bank 1 Main Catalytic Converter’s emissions efficiency has fallen below the minimum allowable limit. This threshold is tracked by a Catalyst Monitoring Oxygen Sensor located on or near the outlet of the Catalytic Converter.
What is Warm Up Catalyst efficiency Below Threshold Bank 2?
Diagnostic trouble code (DTC) P0431 stands for “Warm Up Catalytic Converter, Bank 2—Efficiency Below Threshold.” It means that your car’s primary computer or powertrain control module has detected that the catalytic converter is not efficient enough based on factory specification.
What is Warm Up Catalyst efficiency Below Threshold Bank 1?
The P0421 code means that the powertrain control module is noticing that the catalyst system is not performing as it should during warm up conditions. This time period would be from when the vehicle is first started until about five to ten minutes later.

How do you warm up a catalytic converter?
A very elegant method to speed the warm-up is the use of the engine itself as a “preheater” for the catalytic converters. High exhaust gas enthalpy to raise exhaust system mass up to its operating temperature is obtained by the use of extreme spark retard, stochiometric mixtures, and fully opened throttle.
How do you check a catalytic converter?
Zitat von Youtube: Test is to keep the engine about 2,500 rpm and watch the vacuum gauge if the reading is low or continues to drop this is a good indication that there is a blockage in the exhaust system causing.
