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.

Systems and methods for determining exhibited useful life of sensors in monitored systems

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.
