P0420 2011 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 2011 Nissan Rogue Description
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.
What are the Possible Causes of the DTC P0420 2011 Nissan Rogue?
- Faulty Three-way Catalyst Converter Bank 1
- Exhaust Tube
- Intake Air Leaks
- Faulty Oxygen (O2) Sensor
- Faulty Fuel injector(s)
- Leaking Fuel Injector (s)
- Faulty Spark plugs
- Improper Ignition Timing
- Faulty Engine Control Module (ECM)

2011 Nissan Rogue air condition compressor will not turn on. No voltage to the clutch. Fuse under the hood is good. Any possible causes and/or solutions? Also the check engine light is on. P0420 catalyst system efficiency below threshold Bank 1. Please advise.

The P0420 or catalytic converter should have nothing to do with the Air Condition system. Unfortunately there are many other things that could cause the A/C problem you have, but one of the most common problems is too much or not enough refrigerant. I recommend starting by evacuating and recharging the A/C system with an A/C machine.
For the P0420 code you have to replace the catalytic converter to fix the problem.
