What does Nissan catalyst system efficiency below threshold Bank 1 mean?
P0420 NISSAN Catalyst System Efficiency Below Threshold Bank 1: Code Meaning, Causes, Symptoms, & Tech Notes P0420 NISSAN | Catalyst System Efficiency Below Threshold Bank 1 | 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
How many oxygen sensors does an Altima have?
Your Altima 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 of the converter.
Where is the catalytic converter on a Nissan Altima?
The image above shows the location of the catalytic converter (circled) relative to the exhaust manifold on a Nissan Altima fitted with a QR25DE engine. Note that the manifold and catalytic converter form an assembly, which means that the catalytic converter cannot be replaced separately.
What kind of engine does a Nissan Altima have?
While code P0420 can afflict any application, this code is extremely common on Nissan applications such as Sentra, Rogue, Altima, and other models that are fitted with the QR25DE range of engines, which is widely regarded in the global auto repair industry as one of the worst engines Nissan has ever produced.

What is the definition of catalyst system efficiency below threshold?
As mentioned above, the code’s description is Catalyst System Efficiency Below Threshold (Bank 1). OK, now tell me that again in plain English please…. let’s break it down: the catalyst system being referred to is your three-way catalytic converter; so the catalytic converter is not working properly (i.e. it’s not efficient as it should be).
Why does my Nissan Altima have a catalytic converter?
Catalytic Converter – A catalytic converter is responsible for scrubbing out as much pollution as possible from the Altima’s exhaust. Over time, they can become clogged. Although, modern catalytic converters are supposed to last the life of most vehicles, it could be there is some underlying problem if it has clogged.
