Got a Check Engine Light. Had the code read at Autozone and it came up as a “P0455” “evaporation system large leak” on the read out. Per guideance here checked my gas cap and it was loose.

Safe to assume that this # and explanation corresponds to the loose gas cap I found?

Had them re-set the light and it hasn’t come back on.
