Nissan reports that the fuel gauge on some 2005-08 Frontier, Xterra and Pathfinder trucks built before Sept. 19, 2007 may become erratic, inaccurate or completely inoperative.
According to the car maker, the gauge woes may be accompanied by an illuminated check engine light, with trouble code P0461, P0462 or P0463 logged in the PCM.
A defective fuel-gauge-sending unit is responsible for all the trouble.
Dropping the tank, removing the fuel pump and replacing the sending unit with an updated design, part No. 25060-ZZ00A, should eliminate further gauge issues.
