9.11.3 Function of exhaust gas
temperature sensor
The exhaust gas temperature sensors detect exhaust
gas temperature at the DPF muffler DOC inlet, DPF
inlet, and DPF outlet.
They are mounted in the DPF system and are provided
with the names as indicated in the table below.
DOC inlet Exhaust gas temperature sensor (T
DPF inlet Exhaust gas temperature sensor (T
DPF outlet Exhaust gas temperature sensor (T
The exhaust gas temperature sensors are sensors that
utilize resistance changes based on an NTC thermistor.
When the exhaust gas temperature changes the
resistance of the thermistor at the tip of the sensor
changes.
Then the resistance of the thermistor changes, the
sensor output voltage changes.
The output voltage signal of the sensor is sent to the
engine ECU.
