P0456 OBD code? - Toyota Yaris Forums

Well, just got back from the dealer's and here is the resolution of the P0456 Code: (Quoting from finished repair order)

"Customer states that check engine light is on - check & advise. Cause: Code P0456 Evaporative system leak detected. Very small leak...
Correction: Perform Evap. system check. Perform smoke leak test in evap. system. No leaks found. Reset engine light. Run monitor. No codes found after check out."

They told me that I might not have put the gas cap on correct, but I know I did. Does everyone who has a Yaris notice that the gas cap will only click closed one or two clicks?

What exactly is a "smoke leak tes"??
