Zusammenfassung:	To stably perform an operation of an engine.SOLUTION: An abnormality diagnostic device 100 for a cylinder internal pressure sensor includes a cylinder internal pressure sensor SW6 and a control section (ECU 10). The control section sets a restriction time for restricting an operation of an engine 1 by using a signal of the cylinder inner pressure sensor after fuel supply to the engine is started from a state where the fuel supply to the engine is being stopped during traveling of an automobile.SELECTED DRAWING: Figure 8 【課題】エンジンの運転を安定的に行う。【解決手段】筒内圧センサの異常診断装置１００は、筒内圧センサＳＷ６と、制御部（ＥＣＵ１０）と、を備える。制御部は、自動車の走行中にエンジン１への燃料の供給を停止している状態から、エンジンへ燃料の供給を開始した後に、筒内圧センサの信号を用いてエンジンを運転することを制限する制限期間を設ける。【選択図】図８
