Abstract
The present disclosure relates to a system, apparatus, and method for reconditioning a particulate matter sensor in an exhaust aftertreatment system that will resist poisoning. The system and method includes receiving particulate matter data indicating a state of the particulate matter sensor; determining that the particulate matter sensor is in a full state based on the particulate matter data; activating a heating element of the particulate matter sensor to a multiple of intermittent temperatures that clean the sensor pre-patory to the next measurement. By this manner, many reactive chemicals are removed before they can react with and poison the sensor materials.
