Question

2006 Nissan Xterra V4, fuel sending unit high voltage code po463 can I just change it out in the tank, or is it something else

Answer 1

HI there,

The most common cause of the problem is the fuel sending unit itself. It is possible there is a wiring issue or a problem with the instrument cluster as well. Typically thought the sending unit is the problem Also, contact the nissan dealer, there may be a recall for the sending unit and this code.
