DTC P0461:00: Notes

DTC P0461:00 (L3 WITH TC) DETECTION CONDITION & POSSIBLE CAUSES

DTC P0461:00 Fuel gauge sender unit circuit range/performance problem
DETECTION CONDITION 
  • The PCM monitors the fuel level voltage difference before and after the PCM-calculated fuel consumption has reached 25 L {26.4 US qt., 22 Imp qt.}.  If the difference is 5%  less than the PCM-calculated fuel consumption, the PCM determines that the fuel gauge sender unit range/performance is in error.

Diagnostic support note 
  • This is a continuous monitor (CCM).
  • The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
  • PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle.
  • FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
  • The DTC is stored in the PCM memory.
POSSIBLE CAUSE 
  • Fuel gauge sender unit malfunction or substandard performance
  • Instrument cluster malfunction
  • PCM malfunction
