P0455 Mazda - how do I fix it myself?

Question

How can I fix myself... I need some help with that code? Is there a spray or something to closed the leak? If so, what's the name of it, will it work? Is it a major problem that will break my car down?

Answer 1

check your gas cap, replace it if the seal is dry or cracked. 

Possible causes

- Missing or loose fuel cap

- Incorrect fuel filler cap used

- Fuel filler cap remains open or fails to close

- Foreign matter caught in fuel filler cap

- EVAP canister or fuel tank leaks

- EVAP system hose leaking

- Fuel tank leaking
