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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting sensor malfunction or tampering based on reductant consumption","description":"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 disclose","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11945401","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
