What This Code Means

Low fuel pressure warning message ON; Fuel supply pressure drops below approximately 5 in. water column; Engine shut down; High coolant temperature sensor not sensing high temperature condition; Engine continues to run despite increasing temperatures; Engine shutdown; Low coolant level message displayed; Alarm displayed for five consecutive seconds

Possible Causes

  • Low fuel pressure sensing switch on the fuel regulator opens

  • Coolant level drops below the level of the low coolant level sensor
  • Error condition seen for five consecutive seconds on low coolant level sensor
