Mpv has 133k. But would have hard time starting lately like it needed to crank for a second then last few days wouldn't start but would crank and when you read the codes it u0101 and p0462. Like it was fuel sending unit and tcm. But as soon as it starts up codes go away. Checked fuses seem to be good. Can't find any info on these two codes together. Now the van won't start or crank . And it has battery power its not dimished at all. Assuming it's a electrical problem ? Wouldnt make sense why a fuel sending unit would make it no crank .Any guidance or help greatly appreciated.

 

DTC P0462
Fuel gauge sender unit circuit low input

DETECTION CONDITION

• The PCM monitors the fuel tank level and input voltage from the fuel gauge sender unit when the engine is running. If the input voltage is less than 2.5 V and fuel tank level is full, the PCM determines that the fuel gauge sender unit circuit input voltage is low.

POSSIBLE CAUSE

• Fuel gauge sender unit malfunction
• Instrument cluster malfunction
• PCM malfunction



U0101, can be caused by low battery voltage &/or cycling the key too fast.
