Had a code on my evo programmer today that said my Fuel level Senser error. And it is definately true cause I filled up 3 days ago and now it says I have only 1/4 tank. (Only frome 100kms) I have not yet cleared the code. If I do will that fix the error or do I have to replace the sensor??? If I have to replace it is it in the tank???? I have a 03 f150 supercrew with 5.4l

 

I would try to clear it and se if that maybe be caused by intermittent wiring problem

If it comes back its the sensor
Does this happen at all fuel levels?
