I double-checked the gas cap & reset the CEL. Hopefully it doesn't return but we'll see.

P0455 Evaporative Emission System Leak Detected (large leak)
This code is set if during the evaporative leak check the system fails to reach the evacuation target pressure.
The system will perform additional purge checks to determine the nature of the problem. The additional purge
checks will also run if the leak check fails to complete because the calculated vapour concentration is above
the limit.
Additional Purge Check Enable Criteria:
• Vehicle not stationary
• Load between 30 – 35%
• Purge value >= 75%
Monitor: Until leak check is completed
Potential failure modes
• Fuel filler cap not fitted
• Leak from pipes or connections
• Canister Closure valve stuck open
