CE Light came on the other night while driving. Pulled P0455, I did a reset to see if it comes back, but haven't driven it yet. No gas smell, no drivability issues. If it comes back what is the best place to check next? We don't have gas caps, I did get a warning one time about the fuel filler valve, i cleaned it up and it went away.
The P0455 diagnostic trouble code appears when there’s a leak in the Evaporative Emission Control (EVAP) system, and the system can’t maintain pressure. The EVAP system usually consists of five main components: the fuel tank, fuel cap, vent valve, purge valve, and the evaporative canister (or charcoal canister).
