The Diagnostic Trouble Code (DTC) P0430 indicates a problem with the catalytic converter's efficiency, specifically for bank 2 in a V6 or V8 engine. The sensor related to this code is typically located downstream of the catalytic converter, often referred to as the oxygen sensor or O2 sensor. This sensor monitors the exhaust gases exiting the catalytic converter to determine its efficiency in reducing emissions. If it detects insufficient catalytic activity, it triggers the P0430 code.
