Under sensor check... What is wrong if it show fuel?

I just installed a supra tt fuel pump but have started the car yet. I checked the senors in my pfc and "fuel" is highlighted. It is showing 4.99 volts. Is this normal when changing a fuel pump or is something wrong?
Thanks
Jeremy

The manual (did you read it) states on page 35:

[FUEL] ... Fuel Temp Sensor

Thus if yours is reading full voltage as it is, then either your sensor:
(1) has been pulled for an upgrade to a new secondary rail which the sensor can not be used with like in using the Bosch 1600s
(2) you have a bad sensor
(3) your sensor wiring has an opening in it
