There is a required amount of fuel required by the fuel system to keep the system stable. The amount of fuel required depends on fuel pressure, injection quantity, engine speed, and coolant temperature. The Engine Control Module (ECM) sets Leakage Detected, when the fuel flow exceeds an expected value. When a leak is detected in the system, a counter is initiated. When the counter reaches a predetermined value a fault is set and engine derate is enabled. When the leak is not detected the counter counts down, and once the counter becomes zero the engine is set back to normal running conditions. The Diagnostic Trouble Code (DTC) will set when the counter reaches a calibrated value.
