OBD2 stands for On-Board Diagnostics System, which is a standardized system in vehicles that allows mechanics and vehicle owners to diagnose and identify problems related to emissions, engine performance, and various other systems within the vehicle. The system utilizes a “check engine” light indicator on the dashboard to alert drivers of potential problems.

Code P1441 is related to the EVAP (Evaporative Emission Control System) of the vehicle. It indicates that there is a problem with the secondary air injection system switching valve, which prevents the EVAP system from working properly. This code usually indicates that there is a malfunction in the vacuum switching valve for the EVAP control system. The malfunction could be caused by a damaged valve or an electrical problem. It is advisable to have the vehicle inspected by a qualified mechanic to diagnose the cause and replace any faulty parts as necessary.
