Claim 9:
10. A method for controlling operation of an engine system including a fuel injection system including at least one fuel injector, the method comprising:
energizing the fuel injector to perform a zero-fueling injector operation during operation of the engine, the zero-fueling injector operation including a non-zero injector on-time resulting in operation of the injector but zero fueling by the injector;
determining an injection system pressure drop caused by the zero-fueling injector operation;
modifying at least one fuel injection control parameter in response to the injection system pressure drop; and
using the modified fuel injection control parameter to control injection of fuel by the fuel injector during operation of the engine.
