Abstract
Methods and systems for validating a fluid level sensor having a floating element are provided. First readings are acquired from the fluid level sensor indicative of fluid levels sensed via the floating element during a first period of operation of the fluid level sensor. A validated range of fluid levels for the fluid level sensor is determined based on the first readings. At least one second reading is acquired from the fluid level sensor during a second period of operation, subsequent to the first period of operation. A starting position of the floating element for the second period of operation is determined based on the at least one second reading. When the starting position of the floating element is within the validated range, validating the at least one second reading.
