DTC P115B:00

Low fuel level - forced fuel shutdown

DETECTION CONDITION
•  The PCM monitors the fuel level of the fuel tank using the fuel gauge signal from the instrument cluster. If the total of fuel injection amount calculated by the PCM after the fuel level falls below the E-line is above threshold (greater than P0313:00), the PCM determines that the fuel level is low.
Diagnostic support note
•  The MIL does not illuminate if the PCM detect the above malfunction.
•  FREEZE FRAME DATA is not available.
•  The DTC is stored in the PCM memory.
Note
•  A forced engine stall is detected by the PCM fail-safe function. The PCM after stores this DTC.
POSSIBLE CAUSE
•  No fuel in tank
•  Fuel gauge (in instrument cluster) malfunction
•  Fuel gauge sender unit malfunction
•  PCM malfunction
