What does the code P0420 mean on a Nissan Pathfinder?
P0420 is a very common trouble code. This code number references a number that is given to you when you plug your Nissan Pathfinder into a OBDII scanner. It doesn’t matter which model you have, this OBDII code has the same meaning for all of them (1996+) P0420 is a OBDII trouble code. The code technically stands for:
What does OBDII trouble code mean on Nissan Pathfinder?
P0420 is a OBDII trouble code. The code technically stands for: Your Pathfinder 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.
What does trouble code p0011 mean on a car?
The camshaft (s) is (are) adjusted by the ECM through the use of an oil control valve (s) (OCV) also called variable valve timing control solenoid valves. When trouble code P0011 is set, it means that the intake camshaft in Bank 1 is more advanced than the ECM has told it to be.
What are the oxygen sensors on a Nissan Pathfinder?
Your Pathfinder 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.

What does a catalytic converter do on a Nissan Pathfinder?
Catalytic Converter – A catalytic converter is responsible for scrubbing out as much pollution as possible from the Pathfinder’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.
Why is my Nissan Pathfinder running out of gas?
Whenever the engine is put under a heavy load it’ll feel like it is running out of gas. It’s very similar to the symptoms of a bad fuel filter. Service Engine Light – Often, this is the only symptom of the Nissan Pathfinder P0430 code. There are many things that can cause the P0430 trouble code in your Pathfinder. Here are the most common ones.
What does p0430 mean on a catalytic converter?
P0430 means that the Oxygen sensor downstream of the catalytic converter is registering an improper reading. The upstream and downstream oxygen sensors should show different readings. The computer wants to see that the catalytic converter has scrubbed exhaust emissions.
What’s the engine code on a 2005 Nissan Pathfinder?
My 2005 Nissan Pathfinder began throwing the P0420 and P0430 code randomly over the past couple of months, sometimes frequently and sometimes it would go away for weeks at a time. This is a common code among the VQ40 engines found in the Frontier, Pathfinder, and Xterra.

Here are the most common ones.
What does p0430 mean on a check engine light?
The P0430 is a check engine light code that shows that the efficiency and performance of your catalytic converter are less than the required threshold. This means that every time you turn on your vehicle, you’re adding more pollution to the environment than you should. Several reasons might cause this code to appear.
My 2005 Nissan Pathfinder began throwing the P0420 and P0430 code randomly over the past couple of months, sometimes frequently and sometimes it would go away for weeks at a time. This is a common code among the VQ40 engines found in the Frontier, Pathfinder, and Xterra.
Why does my Pathfinder Xterra keep throwing code?
This is meant for an OFFROAD only application. My 2005 Nissan Pathfinder began throwing the P0420 and P0430 code randomly over the past couple of months, sometimes frequently and sometimes it would go away for weeks at a time. This is a common code among the VQ40 engines found in the Frontier, Pathfinder, and Xterra.
Is it important to fix code P0420?
Repairing error code p0420 is generally inexpensive, so there’s no major cause for concern if it appears. The P0420 diagnostic trouble code is known as a generic fault code. It is set when the Onboard Diagnostic II or OBD II catalyst monitor can sense a drop in its converter efficiency.
What exactly is code P0420?
The definition of the OBD-II P0420 code is ” Catalyst System Efficiency Below Threshold (Bank 1) “. When the ECU stores this code, it means that the catalytic converter is not operating at maximum efficiency and may need replacement. Car fault code: P0420
What is triggering my P0420 code?
P0420 is triggered in the engine control module when there is a problem with the efficiency of the catalytic converter . The engine control unit uses two O2 sensors, one in the front of and one behind the catalytic converter to measure the efficiency of the catalytic converter.
What is check engine code P0420?
In short, engine code p0420 means Catalyst System Efficiency Below Threshold. If your catalyst system isn’t functioning in a proper manner, the ‘Check Engine’ light may be triggered.
