why does my Honda Pilot YF3 (2016-2022) engine light come on after filling gas?

Solution

1. Preparation

• Gather tools: OBD-II scanner, torque wrench, basic hand tools, multimeter, and safety glasses.
• Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Inspect and Replace Gas Cap

• Remove the gas cap and inspect for any visible damage.
• If damaged, replace with an OEM gas cap.
• Reinstall the gas cap securely, ensuring it clicks into place.

3. Check and Repair Fuel Leaks

• Visually inspect the fuel lines and connections for signs of leaks or cracks.
• If leaks are found, replace the damaged sections of the fuel line or components as needed.
• Tighten any loose connections to prevent fuel leakage.

4. Test and Replace EVAP Components

• Use a multimeter to test the EVAP purge valve and other related components for proper operation.
• If any components are found faulty, replace them with OEM parts.
• Clear any error codes from the OBD-II scanner after repairs.

5. Verify Fuel Pressure

• Connect a fuel pressure gauge to the fuel rail.
• Start the engine and check the fuel pressure reading against the specifications in the service manual.
• If pressure is low, inspect the fuel pump and replace if necessary.
