I smell gas when I start my car sometimes and this code came up after a long drive. I went to auto zone and they told me it is a purge valve. I can't figure out where the purge valve is. I think it may be on the firewall on the driver's side. I can't find a video showing me anything. Let me know if you need additional info.

This code usually indicates a large leak in the Evaporative Emission Control (EVAP) system. See diagram attached, refer to #4.

It is generally found near the intake manifold, sometimes on the driver's side of the engine intake runner, near cylinders 3 and 4. It may be partially hidden under the engine cover. It is often bolted directly to the intake manifold.
