Failed emissions test trouble code P0462?

I have a 2004 Ford Taurus that couldn't pass the emissions test due to this code P0462. Is this a faulty fuel level sensor? I had a problem about 1yr ago with the gas gauge showing the empty when it wasn't. But that seems to be ok now. Or could it be a fuel pump? I'm not sure what to do.

The Ford Taurus is an AWESOME ride, dude!

The code is for low input from the fuel level sensor. It's either a bad sending unit or wiring problem. I'd erase the code and drive until the readiness tests are completed and go through emission testing again if the CEL doesn't come back on. The readiness tests usually set with in 100 miles of driving.

See a mechanic to check if the wires feeding the sensor is good and checking if the sensor is providing an output. Most fuel quantitiy sensors are integrated with the pump assembly so you have to put a new fuel pump if the sensor is the cultprit. Put an OEM pump if the sensor/pump is bad.
