ABSTRACT:
An exhaust after-treatment system is disclosed. The system has a particulate trap disposed to remove particulate matter from an exhaust flow of an engine, an upstream temperature sensor disposed to measure a temperature of the exhaust flow upstream of the particulate trap, and a downstream temperature sensor disposed to measure a temperature of the exhaust flow downstream of the particulate trap. The system also has a controller in communication to receive from the upstream and downstream temperature sensors indications of the upstream and downstream temperatures. The controller is configured to compare the upstream and downstream temperatures, determine if the upstream and downstream temperature sensors are improperly swapped based on the comparison, and take a precaution if it is determined that the upstream and downstream temperature sensors are improperly swapped.
