P0420 2010 Nissan Rogue Code - Catalyst System Efficiency Below Threshold Bank 1

Quick Answer

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). Common causes include Faulty Three-way Catalyst Converter Bank 1, Exhaust Tube, Intake Air Leaks. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0420 2010 Nissan Rogue 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. As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase.
When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst malfunction is diagnosed.

Discuss the causes and fixes for P0420 2010 Nissan Rogue OBDII Code

  • 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.
