Code P2424 Nissan Description

The Engine Control Module (ECM) monitors the phase gap between the heated oxygen sensor 2 signal and the heated oxygen sensor 3 signal.
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.
