A P0420 Code means that the engine control unit recognizes that the catalytic converter's efficiency is below the threshold. The ECM uses two O2 sensors, one in the front and one in the back of the catalytic converter, to measure the efficiency. If the efficiency is low, the P0420 code will be triggered. In most cases, a P0420 code is caused. This P0420 obd2 code indicates that there is a problem with the catalytic converter, oxygen sensors or both.

Rotten egg or a sulfur smell |P0420 CHRYSLER Description The Engine Control Module monitors the switching frequency ratio of heated oxygen sensors 1 (front O2 sensor) and heated oxygen sensors 2 (rear O2 sensor).A three way catalyst converter (Manifold) with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2 The P0420 Trouble code. The P0420 Catalyst System Efficiency Below Threshold (Bank 1) DTC is an indicator of problems with the Bank 1 catalytic converter (view on Amazon). This means that the catalytic converter is damaged, worn out, or degraded. Bank 1 means the code is referring to the side of the engine where the number one cylinder is. Since P0420 only refers to an inefficient catalytic converter, it doesn't necessarily mean the catalytic converter is bad. There are other things which can affect the functionality of the catalytic converter, such as a bad oxygen sensor, bad air-fuel sensor, exhaust system leak, engine misfire, abnormal air-to-fuel ratio, and leaded gasoline The most common P0420 and P0430 cause is a clogged catalytic converter filter, which requires replacing the entire catalytic converter. Other causes can include: A faulty or failing o2 sensor. Catalytic converter leaks. Exhaust , intake, or mass airflow (MAF) sensor leaks or other issues

If you're searching for how to fix the P0420 code, your problem is most likely related to issues with the catalytic converter. Since the catalytic converter is very expensive, before you replace it, check issues with other components like the oxygen sensor, the muffler, the exhaust pipe, the manifold, or the oxygen wiring

P0420 is a diagnostic trouble code (DTC) for Catalyst System Efficiency Below Threshold (Bank 1). This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation Code P0420 is without question one of the most common car engine diagnostic trouble codes (DTC). Some also refer to DTC as engine codes, fault codes, troubleshooting codes, etc. Regardless of the specific words one thing is certain - something is wrong Typically the P0420 code triggers the Check Engine Light if the readings of the two sensors are similar. This is indicative of (among other things) a converter that is not working as efficiently as it should be (according to specs).
