PO 463 light in again after fuel sender units replaced

[Jerry32]

I have a 2006 Murano S with approx 66K miles.
In January the service engine light came on and could not view how much gas in the tank along with PO 463-fuel level sensor code after taking to auto parts store.
I took to dealer and had extended warranty which covered the replacement of 2 sender units.Total approx: $540 Parts-$200-Labor $340

A few days ago service engine light on again--went to auto parts store and shows same code-PO 463. No problem this time seeing amount of fuel in tank. car has been driven less than 700 miles since repair.
Any ideas apprerciated-thanks!

Take it back to the dealer. Should still be under warranty.

That relay fuse block is called IPDM, or Intelligent Power Distribution Module. It has been known to cause issues for some members, however non that I can recall with the fuel sending unit. It is worth checking into though.
