  "textContent": "An abnormality detection apparatus for detecting an abnormality of a pressure sensor for a gasoline engine and a diesel engine at an early stage. An ECU 42 checks a difference between a detected suction pressure of a suction pressure sensor 40 and a detected suction pressure of an atmospheric pressure sensor 41, before cranking of an engine 11. When the difference is larger than a dissociation allowable value, the ECU 42 determines that a property of the sensor 40 or 41 deviates from normal operation, prohibits both the detected suction pressures from being used as control parameters of the engine, and sets a value determined in accordance with a running state of the engine 11 instead of the pressures.",
