SERIES 60 EGR TECHNICIAN'S MANUAL
EGR Temperature Sensor
The ECU uses the EGR Temperature Sensor to monitor exhaust gas temperatures in the EGR
delivery pipe and uses exhaust temperature and delta pressure across the venturi tube to determine
rate of EGR flow. The temperature sensor is supplied a 5-volt reference signal from the ECU and
returns a voltage signal to the ECU relative to exhaust gas temperatures in the EGR delivery pipe.
The sensor return voltage decreases as exhaust gas temperature increases (sensor operating values
are 0.10-5.0 V). See Figure 8-23 to view the sensor with connector.
