Very well sounds like the sending unit in the tank. Try running some octane booster and fuel injection cleaner in tank of the truck to loosen any deposits on the float.

Its sounds like the contact switch on the sending unit has gone bad. at the top end of the potentiometer, the wiper has a dead spot, causing the reading to be empty. once the fuel level drops to a level where the wiper contacts a good spot, the gauge reads correctly again. the only fix for this is to replace the sending unit. the check engine light will probably read for a code like "unstable fuel level voltage" or something to that nature, only scanning for the code will tell you for sure. good luck!

The fuel level sensor is at fault and is setting the service engine soon light on. Your local Nissan dealer can repair this under warranty depending on your mileage. The fuel tank will need to be removed to access the sending unit.

2005 Nissan Pathfinder Gas guage malfunction


I just fixed this problem last weekend in my 2005 Pathfinder. It's not the fuel sending unit itself, it's the fuel level sensor that is attached to the sending unit. I'm not a mechanic, but know a little about fixing vehicles and I did it myself in about 2 hours. The dealer may tell you they need to replace the whole fuel sender, but that is false. The sensor costs $80-90 from the dealer or from Courtesy Nissan in Texas. They will ship it to you. You don't need a "special nissan tool" to remove the sending unit, unless they call a hammer and screwdriver "special". It's a simple locking ring. You could probably have any shop do it for $100 labor if you supply the part. You can find instructions if you search Nissan forums. The Frontier has the same problem (since it's the same truck with a different body) so look in Frontier forums as well. Good luck!
