Fault Code P2422: Diagnosis, Symptoms And Causes!
The Evaporative Emissions System (EVAP) prevents gasoline fumes and vapors from being released into the atmosphere. Directs vapors from the fuel tank to the intake where they are burned in the normal combustion process. For this problem as for several others, there is a fault code, which is the P2422 fault code . Knowing it and investigating it would be very useful for you.
The EVAP system has a canister vent valve that allows fresh air into the system. It is normally open unless the powertrain control module (PCM) commands it closed during testing. When the PCM detects that the valve is stuck, the on-board diagnostic (OBD) system will log a P2422 code.
What does the P2422 code mean?
Diagnostic Trouble Code (DTC) P2422 means “Evaporative Emissions System Vent Valve Stuck.”
The EVAP system vent valve is normally open. It only closes when the PCM initiates a test as part of the mandatory OBD-II standards. When the PCM detects that the EVAP system is closed even when it shouldn’t, it will set the P2422 code.
A DTC P2422 could mean that the valve is stuck closed or cannot be opened due to problems with the control system.
Note: The definition of the P2422 code may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact definition of the code.
