Code P0420 2010 Nissan Rogue Description

The P0420 diagnostic trouble code (DTC) for a 2010 Nissan Rogue indicates that the catalyst system efficiency is below the threshold on Bank 1. In simple terms, this means that the catalytic converter is not functioning as efficiently as it should be in reducing harmful emissions from the exhaust gases. The catalytic converter plays a crucial role in converting toxic pollutants into less harmful gases before they are released into the atmosphere. When the efficiency of the catalyst system is compromised, it can lead to increased emissions and potential environmental harm.

Tech Notes for P0420 2010 Nissan Rogue

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). 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.

When is the 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.

  • Nissan Rogue 2010, faulty catalyst-B1, my code is P2423. Is this the same as the P0420 . I've only changed the spark plugs. Trying to get the converter but live in NY. Feedback. TY

  • No the P0420 code is for the Three Way Catalytic Converter and the P2423 for the Hydro Carbon (HC) adsorption catalyst (under floor)

  • My daughter purchased a car. Drove it about 100 miles and overnight parked it. The next morning the check engine light came on. Advance Auto said it was P0420 code. We are seeking what may need to be fixed to correct the code.

  • The problem is more than likely the Three way catalyst converter, but you could start by using high octane gas for about a week to see if that makes any difference.
