P2423 2011 Nissan Rogue Code - HC Adsorption Catalyst Efficiency Below Threshold Bank 1
Quick Answer
The Engine Control Module (ECM) monitors the phase gap between the heated oxygen sensor 2 signal and the heated oxygen sensor 3 signal. Common causes include Hydro Carbon (HC) adsorption catalyst (under floor), Exhaust tube, Intake air leaks. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2423 2011 Nissan Rogue Description
The phase gap between the heated oxygen sensor 2 signal and the heated oxygen sensor 3 signal becomes small as the Hydrocarbon (HC) adsorption catalyst (underfloor) deteriorates.
When the phase gap between the heated oxygen sensor 2 signal and the heated oxygen sensor 3 signal approaches a specified limit value, the HC adsorption catalyst (underfloor) malfunction is diagnosed.
What are the Possible Causes of the DTC P2423 2011 Nissan Rogue?
- Hydro Carbon (HC) adsorption catalyst (under floor)
- Exhaust tube
- Intake air leaks
- Faulty Fuel injector
- Fuel injector leaks
- Faulty Spark plug
- Improper ignition timing
How to Fix the DTC P2423 2011 Nissan Rogue?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
