The engine will be derated.    The engine has electronic unit injectors that are controlled by the Electronic Control Module (ECM). The ECM sends a pulse to each injector solenoid. The pulse is sent at the correct time and for the correct duration for a given engine load and engine speed. Perform the "Fuel System Verification - Test" in Caterpillar Electronic Technician (ET) in order to check the operation of the fuel system.Cat ET also includes the following tests that aid in troubleshooting the injector solenoids:"Cylinder Cutout Test"All active diagnostic codes must be repaired before running the "Cylinder Cutout Test". Use the "Cylinder Cutout Test" to diagnose a malfunctioning injector while the engine is running. When a good injector is cut out, the "Fuel Position" should change. The change in the fuel position is caused by the other injectors that are compensating for the cut out injector. If a malfunctioning injector is cut out, the "Fuel Position" will not change. The "Cylinder Cutout Test" is used to isolate the malfunctioning injector in order to avoid replacement of good injectors."Injector Solenoid Test"Use the "Injector Solenoid Test" to aid in diagnosing an open circuit or a short circuit while the engine is not running. The "Injector Solenoid Test" briefly activates each solenoid. A good solenoid will create an audible click when the solenoid is activated. Cat ET will indicate the status of the solenoid as "OK", "Open", or "Short".
