摘要： A failure detection device for a vehicle having a deceleration deactivatable engine, by which failure detection, performed primarily by monitoring the oil pressure of operation oil, is ensured. The failure detection device is provided for a vehicle having a deceleration deactivatable engine in which it is possible to deactivate at least one cylinder by closing both of intake and exhaust valves thereof by applying the oil pressure of operation oil to a passage for deactivation execution via an actuator, and also it is possible to cancel the closed state of both of the intake and exhaust valves by applying the oil pressure of the operation oil to a passage for deactivation cancellation. The failure detection device includes an oil pressure condition judgement section (steps S204 and S212) which determines whether the oil pressure of the operation oil measured by a POIL sensor satisfies threshold conditions, and an abnormality judgement section (steps S207 and S215) which determines that abnormality exists when it is determined, by the oil pressure condition judgement section, that the oil pressure of the operation oil does not satisfy the threshold conditions.
