Hi,

My Ibiza's MOT is due in the next few days, so of course now is the time the MIL has come on.

I've got the following fault:
1 Fault Found:

7346 - Diesel Particle Filter; Differential Pressure Sensor
P2453 00 [037] - Implausible Signal
Not Confirmed - Tested Since Memory Clear
Freeze Frame:
Fault Status: 00000001
Fault Priority: 2
Fault Frequency: 1
Mileage: 115174 km
Date: 2000.00.00
Time: 00:00:00

Engine speed: 0.00 /min
Normed load value: 0.0 %
Vehicle speed: 255 km/h
Coolant temperature: 71 °C
Intake air temperature: 29 °C
Ambient air pressure: 1000 mbar
Voltage terminal 30: 12.311 V
Unlearning counter according OBD: 40
Particle filter: difference pressure-DIP_PF: 110.03 hPa
Particle filter: offset for differential press.-DIP_PF_AD[0]: 75.04 hPa
Outside air temperature-Ambient temperature: 15.00 °C
Particle filter: soot mass measured-MASS_SOOT_PHY_PF: 9.05 g
Particle filter: soot mass measured-MASS_SOOT_PHY_PF: 9.05 g
Particle filter: soot mass calculated-MASS_SOOT_SIM_PF: 7.10 g
Air mass: actual value:: 0.64 g/s

I had to replace the DPS back in February due to a Short to GND fault, and since then everything has been fine up until yesterday

I've tried searching for solutions, am I right in thinking the only option is to replace the sensor again?

Thanks in advance for any help, and apologies if I've missed any important information
