Hi I just bought an 09 Murano LE everything perfect except the check engine code which I checked myself using the gas pedal trick , 0463 code shows up.


which is concerning the fuel level sensor.


It is true that sometimes my gas gauge indicates an empty tank , then goes back to normal.

So it does have to do with the Fuel level sensor.


Ive checked online but I cant find out if I have to change the full gas pump, just the sensor, etc.

Anyone had this problem ?

thank you

It is common problem on Muranos - fuel sensor inside the gas tank is not working properly (there are 2 of them).

Great DYI is here:

I used it to do mine 3 years ago, $200 for OEM part and 6 easy hours in the garage. I tried to clean it first, it did not helped, so I bought the part and installed it, so far all is working well.

The good part - it is basically a cosmetic problem, which does not affect driving, you can drive your car forever with this code, just have to reset odometers after each fill up.

thanks alot for the help, is it for sure that it is that part that I have to change? since you tell me there are 2 sensors. its weird cause even when my gas tank shows empty it gives me a low fuel warning but with the good mileage left, example .: Empty fuel gauge, warning comes one : only 300 miles left on tank! which is a bit weird, it always reads good the mileage left , but not the actual fuel gauge.

Yes, there are 2 holes under the rear seat with sensor only on the right side and pump-sensor on the left (driver) side. So I had to figure out which one of them was bad.
(parts #1 and #4 on the picture)


Sorry for quoting myself:
Just replaced sending unit based on the great info from this thread.
Couple of notes (Murano 2009):
Part # for passenger side unit 25060-CA01C
Part # for driver side unit 25060-CA00C

Passenger side unit is connected to a main unit (hoze & wiring) so in order to change it I had to open both sides and pull out both units - secondary (pass. side) and primary (on the pump). After that I installed new 2-ndary unit, put all inside, slightly closed hatches and turned ignition to test fuel gauge. It worked - so I didn't have to change the main unit (which is $240 Cad)

Total time first time - several hours, with 90% of work is removal of back seats and opening 2 hatches on the fuel tank.

I suspect my fuel pump might be going too. Every time I fill the car the fuel gauge always ends up above the F. When I bought my MO in 2011 the gauge was lucky to even hit F with a full tank.

Mine always goes above the F in both of my Muranos.

I had time so I used "try and see" method. Bought passenger side sensor, installed it - it worked. If not - I would have bought driver side sensor after that and install it too. I tried to test it with ohm-meter - to no avail.

so no option to change both? Its kinda costly here in canada, 150$ each sensor which comes to 300$

As the fuel level reading plays up on below a quarter of a tank, is the faulty sensor likely to be the "Sub fuel level sensor unit" . Part 1 in the diagream above ???
