Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

The code P0627 indicates you have a Fuel Pump Relay Control Circuit Malfunction . Are you having any fuel pump concerns? The common cause for the codes P0456 and P0440 to set on your 3.3 is in most cases caused by a failing Natural Vacuum Leak Detection Assembly. In order to verify if in fact that is the case you will need to do some testing. I have enclosed the steps in the link below. Copy and paste the links to your browser to open and view them.
