Abstract
Various systems and methods are described for a particulate matter sensor coupled to an exhaust system of an engine. One example method comprises, during a measurement mode, generating a particulate flow rate based on the sensor and adjusting one or more engine operating parameters based on the flow rate. The method further includes, during a reduced contamination mode, heating the sensor to repel particulate from the sensor, and not adjusting the one or more operating parameters based on the sensor.
