If you're behind the wheel of your Chevy Silverado and notice the check engine light illuminated on the dashboard, your first priority should be to safely pull over to prevent any further harm to the engine. Once you've come to a stop, you can utilize an OBD II scan tool to retrieve the code stored in the ECU responsible for triggering the light. In the case that you see a code P0449, it indicates a possible issue with the EVAP vent solenoid. Typically, the solenoid will need replacing if it's detected as malfunctioning, as it may not be operating correctly.
