2007 Pacifica FWD New Cars: what mean km empty...

If you can't put much fuel in i's probably not empty! If there is not a big puddle of fuel underneath then your guage is broken.

Usually just above the pistons in the engine located under the hood.

The most common cause of an inop fuel gauge is the fuel level sender inside the gas tank is defective, this causes the gauge to read empty or just move a little when filled in some cases depending on where the break in the resistor that the float moves is located.

First scanned the PCM in order to know if some fault code is stored there.
