P0464 -P0463

Question

There is a right and left sending unit can you tell by these two codes which one it is or which parts I would be needing

Answer 1

P0463 Fuel level sensor "A" circuit high input

P0464 Fuel level sensor "A" circuit intermittent

This is for the primary pump, Being circuit high and circuit intermittent is a indication of either a failing fuel sending unit or it connection of the sensding unit failing.

 Here is the primary sending unit, being primary it would have the fuel pump with it, it also sends the fuel amount to the fuel gauge on the instrument panel.

Here the secondary sending unit, notice there is no fuel pump. fuel is returned into this side of the fuel tank.
