The pedal message is used to calculate fuel injection.The J1587 and J1939 serial data lines are used as the standard communication link for on-board vehicle instrumentation, off-board service diagnostics and fleet management.The (VECU) Vehicle Electronic Control Unit is linked to the Engine Control Module (ECM) via these data lines. Conditions for diagnostic trouble code (DTC):1) Functional disturbance, idle validation switches2) Accelerator pedal sensor value changes and there is no change in idle validation switch value, or vice versa. Observable symptoms1) Missing kick-down effect2) The engine does not respond when accelerator pedal is pressed. Probable cause1) Accelerator pedal, Sensor2) Wiring harness3)...

The Fuel Pressure Sensor is used to detect low fuel pressure system failures. The sensor consists of a pressure sensitive diaphragm and amplifier. Fuel pressure causes the sensor’s diaphragm to deflect and produce an electrical signal proportional to the pressure. The diaphragm deflection signal is amplified in the sensor.The sensor’s signal is monitored by the Engine Control Module (ECM).The engine control module (ECM) will set a diagnostic trouble code (DTC) if the sensor signal is not within predetermined limits, or the signal is not rational. Conditions for diagnostic trouble code (DTC):1) Fuel pressure critically low Observable symptoms1) Fuel injection can...
