What to do if your Nissan catalytic converter is not working?

Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0420 code is combined with other codes, try fixing the other codes first. Very common problem with Nissan vehicles. There are Nissan factory service bulletins for the following Nissan models:

What does the OBD II fault code P0420 mean?

What Does Code P0420 Mean? OBD II fault code P0420 is a generic code that is defined as ““Catalytic Converter System Bank 1, Efficiency below Threshold”, and is set when the PCM (Powertrain Control Module) detects that the catalytic converter on Bank 1 is operating below a minimum allowable efficiency threshold.

How much does it cost to repair a Nissan P0420?

The cost of diagnosing the P0420 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. When is the P0420 NISSAN code detected? – Three way catalytic converter Bank 1 does not operate properly.

When to use the P0420 warning light?

In most cases, the PCM will set code P0420 and illuminate warning light when it calculates an efficiency value of between 75%, and 70%, with 70% representing the lowest allowable efficiency threshold on most applications. So why does code P0420 affect some Nissan applications more than others?

What does P0420 stand for on Nissan X-Trail?

P0420 is a very common trouble code. This code number references a number that is given to you when you plug your Nissan X-Trail 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 are the most common causes of code P0420?

Note the arrow that indicates the direction of gas flow. What are the common causes of code P0420? The most common causes of code P0420 are many and varied, but could include the following- Failures and/or malfunctions in almost any system, sensor, or component that affects/controls/monitors/regulates combustion, and therefore, exhaust emissions

What causes the P0420 oxygen sensor to read lean?

If the upstream and downstream oxygens sensors are both switching from rich to lean, that’s the sign of a dead catalytic converter. An exhaust system leak really screws up the P0420 testing routing. An exhaust leak near the upstream sensor can cause the downstream sensor to read a steady lean condition.

What causes spark plug to leak on Nissan P0420?
