Bad fuel pressure sensor or bad calibration?

[Cojaken]

I recently ordered and fitted a new replacement VDO fuel pressure sensor part # 41215, for my 3500EM non-S. I did this because the fuel pressure reading became erratic after about 270 hours.

The new fuel sensor reads way too high, over 10 psi running on the electric or mechanical pump.

I know the non-S systems don't allow you to pick the sensor type, but the calibration values are in the ENGINE.AFC file.

Here are the appropriate numbers from mine:

FUEL_PSI.NUM_CAL_PTS, 11
FUEL_PSI.DISPLAY_VALUE_1, 0
FUEL_PSI.AD_VALUE_1, 48
FUEL_PSI.DISPLAY_VALUE_2, 10
FUEL_PSI.AD_VALUE_2, 55
FUEL_PSI.DISPLAY_VALUE_3, 20
FUEL_PSI.AD_VALUE_3, 91
FUEL_PSI.DISPLAY_VALUE_4, 30
FUEL_PSI.AD_VALUE_4, 118
FUEL_PSI.DISPLAY_VALUE_5, 40
FUEL_PSI.AD_VALUE_5, 141
FUEL_PSI.DISPLAY_VALUE_6, 50
FUEL_PSI.AD_VALUE_6, 175
FUEL_PSI.DISPLAY_VALUE_7, 60
FUEL_PSI.AD_VALUE_7, 214
FUEL_PSI.DISPLAY_VALUE_8, 70
FUEL_PSI.AD_VALUE_8, 244
FUEL_PSI.DISPLAY_VALUE_9, 80
FUEL_PSI.AD_VALUE_9, 272
FUEL_PSI.DISPLAY_VALUE_10, 90
FUEL_PSI.AD_VALUE_10, 304
FUEL_PSI.DISPLAY_VALUE_11, 100
FUEL_PSI.AD_VALUE_11, 353

Do they look correct for the 41215 VDO sensor please and if so, do you think the new sensor could be bad?

I’ve checked the ground connection at the sensor and the back of the 3500EM and both are good.

My airplane is an RV- 9A with a carbureted O-320. The previous sensor read about 2.5 psi on the mechanical pump and about 5.5 psi when the electrical pump was running.
