DTC P1319
Misfire with Low/Empty Fuel Drive cycle C:Signal out of range - above maximum.

Possible causes by suggested order of priority:
^ Engine running with very low or empty fuel tank.
^ Misfire occured while fuel low but not empty.

Engine Running With Very Low Or Empty Fuel Tank.
CHECK THE FOLLOWING:
^ The engine was running with a very low or empty fuel tank.
INFORMATION
^ This fault will be logged by the ECM if the engine misfires while the fuel level sensor shows that the fuel tank is low or empty.
^ If the tank runs out of fuel while the misfire diagnostics are active a misfire fault flag will be set. In this case the misfire is caused by the lack of fuel in the tank and no corrective action needs to be taken apart from ensuring that the fuel tank is re-filled.
^ Clear the fault flags after checking for any further non misfire of fuelling faults logged by the ECM.

Misfire Occured While Fuel Low But Not Empty.
CHECK THE FOLLOWING:
^ The fuel level was low but the fuel did not run out at any time.
^ The fuel level sensor is functioning correctly.
INFORMATION
^ This fault will be logged by the ECM if the engine misfires while the fuel level sensor shows that the fuel tank is low or empty.
^ If the fuel did not run out or low enough to cause the misfire then a misfire fault exists.
^ Ensure the fuel tank is filled and that the fuel level sensor no longer indicates empty.
^ Diagnose any misfire faults which are present.
