why am I getting a P0455 code on my Honda CR-V Fifth Generation (2017-2022)

Solution

1. Preparation

• Gather the necessary tools and parts.
• Disconnect the negative terminal of the battery to ensure safety.
• Make sure the vehicle is on a flat surface and properly secured.

2. Inspect and Replace the Gas Cap

• Remove the gas cap and visually inspect it for damage.
• If damaged, replace it with a new OEM gas cap.
• Ensure the new cap clicks securely when tightened.

3. Inspect and Replace EVAP Hoses

• Locate the EVAP hoses; they typically connect to the fuel tank and the charcoal canister.
• If any hoses are cracked or disconnected, replace them with new hoses.
• Use hose clamps to ensure a secure fit.

4. Inspect and Replace the Charcoal Canister

• If the charcoal canister is found to be damaged or blocked, remove it by disconnecting the mounting bolts and the attached hoses.
• Install a new charcoal canister by reversing the removal steps.
• Ensure all hoses are securely connected.

5. Test the EVAP Purge Valve

• Disconnect the electrical connector from the purge valve.
• Apply battery voltage directly to the valve to ensure it opens.
• If the valve does not operate correctly, replace it.
