I'm getting code P0441 and wondering which component to replace first the VSV for EVAP, VSV for Vapor Pressure Sensor or the Vapor Pressure Sensor itself. If I just start replacing parts which one is more likely to fix it. Thank You!!!

There are a number of things that this can be, so we need to start with running through this DTC testing that I attached below.

However, here is a guide that will help with checking vacuum hoses for leaks:

Below is the testing that we need to run through. Basically, we have a possible VSV, hose, wiring connection, or even the ECM. So, let's run through this testing and see what we can find.

Let me know what questions you have. Thanks
