DTC Detection Logic

DTC No.	Trouble diagnosis name (Trouble diagnosis content)	DTC detecting condition	Possible cause
P119A	FUEL PRESSURE SENSOR (Fuel pressure sensor)	All of the following conditions are satisfied: Battery voltage: 8 V or more Under engine start condition Engine coolant temperature at previous ignition switch OFF: 65°C (149°F) or more Engine coolant temperature: 35°C (65°F) or less Temperature difference between engine coolant and intake air: Less than 6°C (42°F) Fuel rail pressure: Less than 1.0 MPa (10.2 kg/cm² , 145 psi) (calculated by ECM) Fuel system monitor: Excessively RICH	Harness or connectors (The fuel rail pressure sensor circuit is open or shorted.) Sensor power supply 3 is shorted Fuel rail pressure sensor
