The subject matter of the invention is a method for detecting the blocking of at least one inlet valve in the closed position in an indirect injection system of a motor vehicle, the vehicle being provided with an internal combustion engine comprising cylinders each fitted with an inlet valve and an exhaust line provided with a catalyst, characterised in that the method comprises: - an injection of fuel into at least one cylinder of the engine by the opening of the inlet valve of the cylinder, said injection resulting in the combustion of the fuel if the inlet valve is open, - stopping of the injection in all the cylinders, - after the stopping of the injection, a step to detect if combustion is taking place in the engine or in the catalyst, - detecting the blocking of at least one inlet valve in the closed position if combustion is detected in the engine and/or in the catalyst. |
