Which everyday cause triggers a leak code most often?

  • A.Nothing
  • B.The fuel filler cap left loose or omitted after refuelling, since it forms part of the sealed system
  • C.A loose or missing filler cap
  • D.A cracked canister, which is the commonest fault within the evaporative system of a modern vehicle

Answer: C

The cap seals the system and a loose one fails the test immediately. The last option explains exactly why, which makes it a correct and more instructive version. Many vehicles now warn specifically about it. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb. Tracing the requirement back to the physical constraint that produces it makes the answer follow. Most errors here come from carrying a result across from a neighbouring case where it does not hold.
