Answer 1

The P0455 it’s a very common code, because the code is set if the gas cap is loose or missing. Start by tighten the gas cap and clearing the code. In most cases the code can be clear by disconnecting the car battery for about 30 minutes. 

 

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
