What is the meaning of OBD-II code P0420, and what is the possible cause of this code being generated?
The OBD-II code P0420 refers to a malfunction in the catalytic converter's efficiency. This code is generated when the Engine Control Module (ECM) detects a discrepancy between the air-fuel ratio sensor's signal and the oxygen sensor's signal. This discrepancy can be caused by various things, such as a malfunctioning catalytic converter, a clogged air filter, a vacuum leak, or an issue with the fuel system. In order to diagnose and fix the problem, a mechanic will typically perform a visual inspection of the vehicle's exhaust system and use a scan tool to retrieve the stored diagnostic trouble codes. Depending on the cause of the code, the mechanic may need to replace the catalytic converter, repair the vacuum leak, or perform other repairs to resolve the issue.
