my Toyota Camry Eighth Generation (2018-present) has a check engine light and P0455 code what to do

Solution

1. Preparation

• Tools Required: OBD-II scanner, smoke machine, multimeter, socket set, and screwdrivers.
• Disconnect the battery to ensure safety while working on the EVAP system.

2. Inspect and Replace the Fuel Cap

• Remove the fuel cap and inspect the rubber gasket for wear or damage.
• If the gasket is worn, replace the fuel cap with a new one that meets OEM specifications.
• Reconnect the battery.

3. Repair EVAP Hoses

• If any cracks or breaks are found in the EVAP hoses, replace the damaged hoses.
• Use hose clamps to secure any new hoses in place, ensuring a tight fit.

4. Smoke Test the EVAP System

• Connect the smoke machine to the EVAP service port.
• Introduce smoke into the system and visually inspect for leaks.
• If leaks are detected, repair or replace the affected components (e.g., hoses, canister).

5. Test and Replace the Purge and Vent Valves

• Use a multimeter to check the resistance of the purge valve and vent valve; compare readings to specifications in the repair manual.
• If either valve is faulty, replace it with a new one.
