Self diagnostics of a particulate matter sensor |
摘要 |
A particulate matter sensor includes first and second electrodes spaced from each other with a bias resistor connected between the first and second electrodes. The particulate matter sensor allows an open circuit fault condition in the sensor or in the connectors or wiring to the sensor to be detected. A sensing system using the particulate matter sensor and a method for diagnosing faults in a sensing system are also provided. |
