2005 nissan pathfinder fuel light wont turn off tank is full

There is plenty on the internet on recalls for deformed fuel tanks
from 04 thru 08

Should get a new sending unit free from the dealer on a federal
recall.

On an 03 ,if that is what you have, you will have to some testing
Maybe the sending unit just wore out

Google bod code P0183 and this will tell you the answer

I know that there is a recall for the Armada concerning this issue. You may want to check with Nissan to see if there is a TSB-trouble service bulletin as well for the Pathfinder

There may be an updated sensor to install refer to service bulletin 07-069A your dealer can find it for you.

you will have to locate the breather pipe for you fuel tank and clean it, it sounds like it is blocked

Could be the float level in tank is disconected, or fuel gauge fuse is blown, or gauge itself is malfunctioned.

if it will crank but not start check the ignition components and fuel pressure if it wont even crank check fuses and all starting system electrical connections and components

check instrument voltage stabilizer.

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!

yup, nissan has problem with those and yes, there is a service bulletin for the replacement of the fuel level sensor. common problem on your year pathfinder and frontier.
