The sensor mode selection module selects a regeneration mode for the particulate matter sensor from among a plurality of operation modes. The regeneration mode regenerates the particulate matter sensor. The heater power detector determines a voltage output based on a voltage applied to the particulate matter sensor. The voltage output corresponds to operation of the particulate matter sensor in the selected mode. The protection tube diagnostic module performs a diagnostic of the particulate matter sensor. The protection tube diagnostic module selectively diagnoses a fault in the particulate matter sensor based on the voltage output determined during the regeneration mode and a regeneration power threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Particulate matter sensor diagnostic system and method","description":"A diagnostic module for diagnosing a particulate matter sensor in a vehicle includes a sensor mode selection module, a heater power detector, and a protection tube diagnostic module.
