getting a DTC code 462 low input ckt A after replacing fuel

Is the OB2 code a 0462? If so it's Fuel Level Sensor Circuit Low Input..There's a Fuel Level Module/Sensor directly behind the Radio/Heater Controls.You must remove the Radio etc. to get to it,it's a small black box of sorts with a electrical connection to it as well as 1 mounting bolt that holds it.This also when it goes bad will make your fuel gauge read as high as it will go among other readings,as well as set the code for 0462.Just replaced one on a 2000 Taurus Flex Fuel System...And it solved the problem on this particular car..
