P0420 OBD-II Trouble Code: Catalyst System Efficiency Below Threshold (Bank 1) Cost of diagnosing the P0420 code P0420 is a diagnostic trouble code (DTC) for "Catalyst System Efficiency Below Threshold (Bank 1)".

P0420 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.

Trouble Code - P0420 Catalyst System Efficiency Below Threshold (Bank 1) Welcome to P0420.com, the place dedicated to that DTC (diagnostic trouble code) P0420 . The P0420 code is a very popular one and that's why there's a site dedicated to that specific trouble code.

In your case, the P0420 code stands for “Catalyst System Efficiency Below Threshold (Bank 1).” When you receive a P0420 code it means your catalytic converter is not operating at maximum efficiency. Usually this means your catalytic converter needs to be replaced or there is a problem with your O2 (oxygen) sensors.

P0430: Catalyst System Efficiency Below Threshold (Bank 2) The P0430 check engine light code, like P0420, means the catalyst system efficiency is below the required threshold. Simply put, this means your car is adding more pollution into the air than it’s supposed to. This can be caused by a fuel system problem, a clogged catalytic converter, damaged O2 sensors or a combination of all three.

FYI this code is identical to P0430 however that code is for bank 2. You may even find you have both P0420 and P0430 trouble codes at the same time. When is the P0420 code Detected? Three way catalytic converter Bank 1 does not operate properly. – Three way catalyst converter Bank 1 does not have enough oxygen storage capacity.

Catalyst effiency below threshold p0420 bank 1. You will need have the computer data read to see if the converter is doing its job or if the sensor has failed. Most times it is the converter itself.The system uses a oxygen sensor before the cat and a monitor after.The monitor tells the computer if the cat is functioning properly. If it is not it sets the efficiency codes.
