2003 nissan sentra 1.8L i know the gasket header is bad already. service engine soon light comes on and p0462,p0462 P comes on. what parts do i need?
-
If at some point the fuel level got too low, then that may be reason you got the P0462 and you could just try clear the code. If the fuel level never got too low, then you may have to replace the "Fuel Level Sensor" inside the tank.
-
it wont clear thats the problem i have i refilled the tank and checked all the fluids theyre all good but the code and light wont clear
-
If it doesn't clear, then you have to replace the "Fuel Level Sensor" to fix the problem.
