A power system for a work vehicle includes an engine that generates exhaust gas, an exhaust treatment system that treats the exhaust gas, and an electronic control system coupled to the engine and the exhaust treatment system and implementing a maintenance management system. The maintenance management system is configured to receive a first identifier associated with a first sensor or actuator device installed in the exhaust treatment system, store the first identifier in memory, receive a second identifier associated with a second sensor or actuator device installed in the power system of the work vehicle, compare the first identifier to the second identifier to determine that the first identifier differs from the second identifier and that the second sensor or actuator device is a replacement for the first sensor or actuator device in the exhaust treatment system, and clear any fault codes associated with the first sensor or actuator device.
