Unhappy chevy s10 sensor error code po452

my service engine light comes on. read code po452, fuel tank pressure low.
Does this mean sensor is bad or what else is relative to this problem???
The reader pointed directly to this sensor. (evaporative emission system pressure sensor switch low)
i had recently put in a new fuel pump also,.

Was that code on before you replaced the pump? If so did you reset the ecm?
