This is an issue with the evaporative emission system. It is recommended to check whether the charcoal canister purge valve is malfunctioning. For a quick diagnosis of the trouble code, it is advisable to visit a repair shop to read the trouble code and identify the source of the issue for repair.

When I encounter the P0496 trouble code, the solution is to troubleshoot the exhaust gas recirculation (EGR) system. Excessive EGR flow is often caused by a stuck or dirty valve. Open the hood, locate the EGR valve position; use a wrench to remove it, and check for stickiness or carbon buildup blockage. I spray carburetor cleaner inside, let it dry, and reinstall it—this fixes most of my cases. If cleaning doesn’t work, check the vacuum lines for leaks or blockages, as cracked hoses are common. After cleaning, use an OBD scanner to clear the code and restart the car, then drive a few laps to confirm it doesn’t reappear. Regular inspection of the emission system can prevent issues, otherwise, it may affect vehicle performance or even increase emission costs. It’s recommended to check the valve condition every six months.
