Abstract: A method executed by at least one server, comprising: receiving, from a first monitored system comprising an internal combustion engine and a first sensor, a first signal associated with a first occurrence and a second occurrence of an internal combustion engine event and first measurement data of the first sensor; determining a first measurement from the first measurement data and a second measurement from the first measurement data based on the first and second occurrences, respectively; determining a reference measurement; determining a first reference deviation; determining a second reference deviation; after determining the first reference deviation is less than a first reference threshold and the second reference deviation is less than a second reference threshold, determining a measurement deviation; comparing the measurement deviation to a measurement threshold; and after determining the measurement deviation satisfies the measurement threshold, determining a first exhibited useful life of the first sensor.

Abstract: At least one server comprising at least one processor coupled to at least one memory storing instructions. The server can receive a first signal from a first monitored system comprising an internal combustion engine and a first sensor, the first signal associated with a first occurrence of an internal combustion engine event, a second occurrence of the internal combustion engine event, and first measurement data of the first sensor. The server can determine a first measurement from the first measurement data. The server can determine a second measurement from the first measurement data. The server can determine a measurement deviation between the first measurement and the second measurement. The server can compare the measurement deviation to a stored measurement threshold. The server can determine a first exhibited useful life of the first sensor based on the measurement deviation and at least one of the first measurement or the second measurement.
