Title:
筒内圧センサの故障診断装置
Document Type and Number:
Japanese Patent JP7035916
Kind Code:
B2
Abstract:
A failure diagnosis system is provided, which includes an in-cylinder pressure sensor, a fuel injection valve, an engine controller including an engine control module and a diagnosis module. The engine control module controls the fuel injection valve to stop the supply of fuel to the engine, when a fuel cut condition is satisfied while the automobile travels. The diagnosis module includes a limiting module configured to limit an execution of the failure diagnosis of the in-cylinder pressure sensor until the diagnosis module determines that a given period has lapsed after the stop of fuel supply to the engine. The diagnosis module reads a signal of the in-cylinder pressure sensor when the given period has lapsed after the stop of the fuel supply to the engine, and diagnoses the failure of the in-cylinder pressure sensor based on the read signal of the in-cylinder pressure sensor.
