• Diagnostic code 1797-4 Fuel Rail Pressure Sensor voltage below normal is not active.
• No diagnostic codes are active for the fuel rail pump.
• No diagnostic codes are active for the fuel injectors.
System Response:
The warning lamp will be illuminated and the diagnostic lamp will flash the event code.
The event code will be logged.
