2350 7th injector pressure sensor keeps failing

[koliunia]

Hello everyone. I'm wondering if anyone has had an after-treatment fuel pressure sensor failing multiple times. The engine harness has been replaced with a new manifold and new sensor. All oem parts. Three months later, the sensor failed again. The owner refuses to update the ECM, so it is not been updated since new (2015). Can someone explain how that engine developed a habit of consuming a sensor?
