P2423 2008 NISSAN ROGUE Meaning

The Engine Control Module (ECM) monitors the phase gap between heated oxygen sensor 2 signal and heated oxygen sensor 3 signal.
The phase gap between heated oxygen sensor 2 signal and heated oxygen sensor 3 signal becomes small as the Hydro Carbon (HC) adsorption catalyst (under floor) is deteriorated.
When the phase gap between heated oxygen sensor 2 signal and heated oxygen sensor 3 signal approaches a specified limit value, the HC adsorption catalyst (under floor) malfunction is diagnosed.
