Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

P0446 sets when the fuel tank pressure sensor detects to much vacuum in the fuel tank.This can be an issue with a damaged fuel tank valve or vent valve ( canister close valve) or a restricted charcoal evap canister itself at fault needing replaced.

There was a bulletin released on your model here for more enhanced diagnosis.You have to have this diagnosed/tested further to locate which component is causing this issue.In some cases the fuel tank has to be removed to do the proper testing.

But this will need to be tested further to locate and repair this issue here as one of these will be the cause needing repaired or replaced.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
