P0433

DTC P0433, sometimes indicated as P043300 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the auxiliary emissions system causing heated catalyst efficiency below threshold (bank 2).

This code is set when the engine's computer (ECM) detects that the heated catalyst on bank 2 is not performing up to standard. This can be caused by a number of factors, such as a blocked exhaust, a defective catalyst, or a misfiring engine.
There are a few things that you can do to try and fix this code:
-Check the exhaust system for any blockages, and clear them if necessary
-Check the catalytic converter for any damage or defects, and replace it if necessary
-Check the engine for any misfires, and fix them if necessary
