Well. I DTC the code that my car is throwing off, It is a fuel sensor code I think....PO463...can anyone collaborrate and also what can fix this....The dealer told me to use chevron Techron to fix......today I put it in...but it is still showing as gas tank empty and throwing this code.....do I need to worry...or shoudl this problem be fixed with the cleaner....if the cleaner does not work what will ford do>> replace what..it says it is from a high PCM input according to reading the code...the dealer stated sulfur deposits....and techron will repair....I guess time will tell....any insight will be very helpful

P0463 Fuel Level Sensor Circuit High Input is the official explanation of the code..is this simply sulfur or larger issues....again any input very helpful...currently running Techron through..but if that does not work what should dealer do next..

 

run a tank or two first , if it dosent work ,then bitch like mad.

 

Ford added a solution to my gas tank and the problem was solved. This is common.

 

yup...problem solved with Techron......damn Mobil sheatty gas

 

P0463 Fuel Level Sensor High Input

 

Dunno if it's the same thing, but I've had the problem where an aggressive turn throws off the fuel guage sensor into reading just barely above empty. I took it into Ford for the tsb and they claimed to have fixed it, but it still does it anyways. I generally just take her sideways the opposite way and it fixes it, or I try and see if I can go negative in the "Miles until empty" readout (but it never does ).

I haven't noticed Techron fixing it.

 

problem was solved until refilled today...now it is happening again....URRGGGGGGGG!!!!!!!!!!

 

BUMP...put back on stock air box....and return to stock tune....then restarted and of course it is now going to be a ***** and not throw the code.....still going to bring it in....what will they do...replace the sensor...replace the sending unit...fuel pump...???anyone have the problem continue???

 

did you refill using the same brand of gas?

 

no...refilled with Chevron 93 with techron....then even added another bottle of techron......it only did it at full then all day today....I called dealer yesterday..he said they will fix it..but try not to have too much gas in it....so it is now at hair under 3/4 ....retuned to stock....stock air box and NO CODES>>.....urrgghhh>!!!!!!!!!!!!!!! now it hopefully will throw a code before I go back to dealer Tuesday..otherwise they will claim they can not simulate the code so cant fix..albeit this is my 2nd time with this TSB problem....
