DTC DETECTION LOGIC

DTC No.	Trouble diagnosis name (Trouble diagnosis content)	DTC detecting condition	Possible cause
P1197	FUEL RUN OUT (Out of gas)	Fuel rail pressure remains at 1.5 MPa (15 bar, 15.3 kg/cm² , 217.5 psi) or less for 3 seconds or more with the fuel level too low. Fuel rail pressure remains 2.7 MPa (27 bar, 27.5 kg/cm² , 392 psi) lower than a target fuel pressure for 5 seconds or more with the fuel level too low. Fuel rail pressure remains at 0.23 MPa (2.3 bar, 2.346 kg/cm² , 33.35 psi) or less for 5 seconds or more with the fuel level too low. NOTE: Allow engine coolant temperature to reach 70°C (158°F) or more once.	Out of gas Harness or connectors (The low pressure fuel pump circuit is open or shorted.) Low pressure fuel pump Fuel pressure regulator Low pressure fuel system Low fuel pressure sensor Harness or connectors (The high pressure fuel pump circuit is shorted.) High pressure fuel pump High pressure fuel system Fuel rail pressure sensor Disconnection of the fuel hose
