A fuel vapor treatment apparatus of a vehicle in which a supercharger that supercharges intake air is provided at an intake passage of an internal combustion engine includes a pump controller that drives a pump, a gas passage pressure detector that is provided between a canister and the pump in a gas passage and detects pressure of the gas passage, and an abnormality determining module that determines whether an upstream-side purge passage has an abnormality, on the basis of the pressure detected by the gas passage pressure detector. The pump controller drives the pump when an upstream-side valve is in an opened state. The abnormality determining module determines whether the upstream-side purge passage has an abnormality, on the basis of the pressure detected by the gas passage pressure detector after the upstream-side valve enters the opened state and the pump is driven. |
