Exhaust Gas Temperature Sensors

•
The three exhaust gas temperature sensors (upper/middle/lower) are located in the
combined housing of the oxidation catalytic converter/DPF and detect the temperature of
the exhaust gas upstream of the oxidation catalytic converter, as well as upstream and
downstream of the DPF. Each sensor is a temperature-resistive resistor with NTC, i.e. its
resistance becomes smaller when the temperature rises. The exhaust gas temperature
sensor supplies the PCM with an analogue voltage signal between 0...5 V.
