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.
