System malfunction location |
Fuel gauge sender unit circuit low input |
||||
|---|---|---|---|---|---|
|
Detection condition
|
• The PCM monitors the fuel level signal and fuel gauge sender unit output voltage from the instrument cluster. If the PCM detects that the fuel level, fuel gauge sender unit, or fuel gauge sender unit (SUB) output voltage is too low, the PCM determines that the fuel gauge sender unit or fuel gauge sender unit (SUB) circuit has a malfunction.
