why does my Renault Clio V (2019-Present) check engine light come on after filling gas?

Solution

1. Preparation

• Gather tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace Fuel Cap

• Remove the fuel cap and inspect the rubber seal for cracks or wear.
• If damaged, replace the fuel cap with an OEM part.
• Reinstall the new fuel cap, ensuring it clicks securely to create a proper seal.

3. Check Evaporative Emissions System

• Locate the EVAP canister and inspect it for cracks or damage.
• Replace the EVAP canister if necessary.
• Use a smoke machine to check for leaks in the EVAP lines. Repair any detected leaks.

4. Inspect Fuel System Components

• Visually inspect fuel lines for signs of wear or leaks.
• Tighten any loose connections and replace any damaged hoses or fittings.
• If the fuel filler neck is damaged, replace it.

5. Reconnect Battery and Clear Codes

• Reconnect the battery.
• Use the OBD-II scanner to clear any stored error codes.
• Start the engine and allow it to reach operating temperature.
