摘要： A method of testdiagnosing the operation of each of a plurality of fuel injectors of an internal combustion engine system includes inhibiting ignition of the engine, monitoring a fuel pressure within a fuel rail of the engine and pulsing a fuel injector of the plurality of fuel injectors of the engine. Whether the fuel pressure has stabilized is determined and a pressure differential is calculated based on a pre-pulse fuel pressure and a post-pulse fuel pressure when the fuel pressure has stabilized. A technician determines whether the fuel injector is operating properly based on the pressure differential.

摘要： A control system for a vehicle comprises a throttle control module and a diagnostic module. The throttle control module controls a position of a throttle of the vehicle and compensates for changes in effective opening area of the throttle due to coking. The diagnostic module reports a coking value to a user based upon an amount of compensation performed by the throttle control module. A method comprises controlling a position of a throttle of a vehicle; compensating for changes in effective opening area of the throttle due to coking; and reporting a coking value to a user based upon an amount of compensation performed.
