Small correction, that is the tank pressure sensor, not fuel pressure sensor.
P0453 doesn't typically represent a problem with the sensor itself.
Here is the diagnosis procedure.
P0453 Above upper limit – Short circuit to B+
Diagnosis
Check wiring from pressure sensor to DME control module for short to B+.
check wiring harness for chafing and pinching damage.
