Question

How can I fix it code p1456

Answer 1

This code means there is an evap emissions leak in the evap system. This could be as simple as a loose gas cap or something a little more complicated. Check the fuse cap and make sure it's in good condition. If it is, and it's tight, you might want to consider having a smoke test done to locate the leak. Here is some more info on the code
