Question about 2000 Ford F150 Flareside SuperCab
What P0453 -Evaporative Emission Control system pressure Sensor High Input means?
P0453 is for the fuel tank pressure sensor. This code means that the voltage on the sensor was greater than 4.5V during key on engine off or during any engine operating mode.
Normal voltage from this sensor with no vacuum or pressure on the system should be 2.37 to 2.97V.
PCM sends a reference voltage of 5V to the sensor and tells if there is pressure or vacuum in the fuel tank by the voltage that returns from the sensor.
Possible causes are:
Usually it is a loose connector at the sensor or a bad sensor.
It mounts on top of the fuel tank,has a 3 wire connector. To replace it you have to push down on it and twist,if I remember right CC.

I was getting the same code on my F-150 and it is the evaporated emissions pressure control sensor. this reads the fuel pressure in the fuel tank. possible bad sensor.but sometimes just a bad connection on top of fuel tank where sensor plugs in.
