HOW IT WORKS

Postprocessing preheat diesel oxidation catalyst inlet and outlet temperature sensor /
postprocessing diesel particulate filter (DPF) inlet and outlet temperature tensor are mounted
on the exhaust pipe, is an intelligent equipment. It send a value to the engine control module
ECM via the J1939 data communication interface. By performing an autonomous internal
diagnosis, returning the fault report to the main ECM. The preheat diesel oxidation catalyst
inlet temperature sensor perform autonomous internal diagnostics and send the fault reports
back to the main ECM via the J1939 data communications interface. Postprocessing preheat
diesel oxidation catalyst inlet and outlet temperature sensor / postprocessing diesel particulate
filter (DPF) outlet temperature tensor permanently fix on the postprocessing preheat diesel
oxidation catalyst temperature sensor and postprocessing diesel particulate filter (DPF)
temperature tensor module. They work as a single unit and cannot be replaced separately.
Postprocessing preheat diesel oxidation catalyst inlet and outlet temperature sensor is used
by the ECM to monitor the temperature of the engine exhaust flowing into the preheated
diesel oxidation catalyst.The postprocessing preheat diesel oxidation catalyst inlet and outlet
temperature sensor monitor the temperature of the postprocessing system and determine
whether the postprocessing catalyst is missing. Postprocessing preheat diesel oxidation
catalyst inlet and outlet temperature sensor / postprocessing diesel particulate filter (DPF)
inlet and outlet temperature tensor module connect directly to the battery power and ground.
