A systems for detecting level sensor malfunction or tampering based on reductant consumption and determining when to initiate a quality check of reductant used in an aftertreatment system are disclosed. The system comprises a memory storing instructions and a processor executing the instructions to perform a process including: receiving dosing data associated with an amount of DEF supplied to the aftertreatment system; receiving tank level data from a level sensor in a DEF tank; comparing the dosing data with the tank level data; and based on the comparison: initiating, by the one or more processors, a quality check; and/or determining, by the one or more processors, a possible error requiring further diagnostics; and causing to present, by the one or more processors, an indication that the quality check is being initiated and/or that a possible error requires further diagnostics on a display.
