                 Description

                 1 .    The postprocessing system is monitored by a temperature sensor located in
                        the exhaust system.The postprocessing DOC inlet temperature sensor is located
                        behind the turbocharger outlet.The postprocessing DPF inlet temperature sensor
                        is located between the postprocessing catalyst and the postprocessing
                        particulate filter.The postprocessing DPF outlet temperature sensor is located
                        behind postprocessing particulate filter.These sensors monitor the temperature
                        of the postprocessing system and determine whether the postprocessing catalyst
                        is missing.
