P0451 2011 Ford Fusion -

Question

I had my ford fusion oiled and after the engine light came on.I had my friend check for a code and these codes came up,PO451 and P1450

Answer 1

Hi there,

The code P1450 indicates there is to much vacuum being pulled. This could be a problem with the vent control valve or the purge control valve.

The second code is for the fuel tank pressure sensor. This code may appear if there is another issue in the system which there is in your case.

This should not have anything to do with your oil change. These are emissions codes and will happen if there is a problem and the car does a self test. The computer determines when to do the self tests.
