  "textContent": "An evaporated fuel processing may include: a canister disposed on a purge passage; a control valve disposed on the purge passage between an intake passage and the canister and switching between communication and cutoff states, the communication state where the canister and the intake passage communicate through the purge passage, and the cutoff state where communication between the canister and the intake passage is cut off on the purge passage; a pressure detector detecting a pressure in the purge passage on a canister side relative to the control valve; and a determining unit determining whether clogging is occurring in the purge passage between the control valve and the intake passage by using a difference between a pressure under the communication state and a pressure under the cutoff state that are detected by the pressure detector while the control valve repeatedly switches between the communication state and the cutoff state.",
