Abstract:
The vehicle is a hybrid vehicle capable of traveling using motive power of at least one of an engine and a motor generator. The vehicle includes: a fuel pump; an injection valve injecting fuel supplied from the fuel pump to the engine; a fuel pressure sensor detecting a supply pressure of the fuel generated by the fuel pump; and an engine ECU.The engine ECU performs a fuel pressure increasing process of increasing the supply pressure of the fuel generated by the fuel pump, and conducts a fault diagnosis of the fuel pressure sensor based on a value detected by the fuel pressure sensor during the fuel pressure increasing process. The engine ECU conducts the fault diagnosis of the fuel pressure sensor in a case where the engine is being stopped and a vehicle speed is higher than a threshold value.
