EGR Temperature Sensor: Testing and Inspection

CIRCUIT DIAGRAM





INSPECTION USING SCAN TOOL











HARNESS INSPECTION PROCEDURE

COMPONENT TEST PROCEDURE
1. Remove the EGR temperature sensor.





2. Place the EGR temperature sensor in water, and then measure the resistance value between terminals 1 and 2 while increasing the water's temperature.

3. Replace the EGR temperature sensor if there is a significant deviation from the standard value.

60-83 K Ohms at 50°C (122°F)
11-14 K Ohms at 100°C (212°F)

4. Install the EGR temperature sensor, tighten to specified torque.

Specified torque: 10-12 Nm (7.3-8.6 ft lb)
