  • Method for testing the operation of a pressure sensing unit of an injection system of an internal combustion engine
    Patent number: 8113039
    Abstract: In a method for testing the operation of a pressure sensing unit of an injection system of an internal combustion engine, the injection system has no high-pressure valve. An error is detected when a pressure gradient value falls below a pressure gradient limit while at the same time the most recently detected pressure is higher than a pressure limit.
