Its Evaporative Emission Control System Tank Detected (gross leak)

Causes

A code p0455 most likely means one or more of the following has happened:

* A loose or improperly affixed gas cap

* A non-conforming gas cap (i.e. not factory/original brand)

* Other leak or damaged piece in EVAP system

Possible Solutions

With a p0455, the most common repair is to:

* Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.

* Otherwise, replace the gas cap, and/or

* Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary
