EGR Temperature Sensor: Testing and Inspection

INSPECTION

1. Remove EGR valve.
2. Remove EGR gas temperature sensor.





3. Inspect EGR gas temperature sensor.
Using an ohmmeter, measure the resistance between the terminals.

Resistance:
At 50°C(122°F): 64 - 97 K ohms
At 100°C (212°F): 11 - 16 K ohms
At 150°C (302°): 2 - 4 K ohms

If the resistance is not as specified, replace the sensor.
4. Reinstall EGR gas temperature sensor.
5. Reinstall EGR valve.
