P0420 infiniti code.

I've cured many a car with P0420 and P0430 with a tune up. Sometimes it has been spark plug coils which gets a little more expensive, but new spark plugs is the best place to start. The list of things that can cause P0420 to become active is everything from a dirty MAF sensor to an exhaust leak and everything in between.A P0420 code is set when the upstream sensor and the downstream oxygen sensor sense the catalytic converter is not doing its job. Basically, the amount of oxygen going into the converter is not being burned, and it detects it through the downstream sensor. Oxygen is the key here. Modern Engine Management Systems leave a little bit of …Chevrolet P0420 OBDII Code Defined. P0420 is an OBDII trouble code. The code technically stands for: Catalyst System Efficiency Below Threshold. Your Chevrolet has at least two oxygen sensors, one before and after the catalytic converter. Among the many jobs that oxygen sensors have is they have to measure the emissions levels coming in and out ...Tech Notes. As the code description implies the P0420 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting).

Code P0420 2007 Toyota Prius Description. The Engine Control Module ( ECM) 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.When the P0420 code appears, the catalyst system efficiency is below the threshold for a particular engine bank, often referred to as Bank 1. This code is related to the vehicle's catalytic converter and oxygen sensors. The primary purpose of a catalytic converter is to reduce harmful emissions from the engine by converting toxic gasses, …The P0420 code indicates a problem with the catalytic converter. This is typically caused by reduced efficiency due to clogging or damage.

P0430 catalyst below efficiency bank 2 comes on periodically. (There are no other codes being thrown.) I put a data logger on it today on my drive to work and the rear sensor is certainly erratic at times. It doesn't necessarily follow the front sensor signal. I thought the most reasonable way to test it would be to swap the sensors side to side.
