EGR Temperature Sensor: Testing and Inspection

EGR GAS TEMPERATURE SENSOR INSPECTION

1. Remove throttle body.





2. Remove EGR gas temperature sensor.
3. Inspect EGR gas temperature sensor.





Using an ohmmeter, measure the resistance between the terminals.

Resistance:
64 - 97 K ohms at 50°C(122°F)
11 - 16 K ohms at 100°C(2i2°F)
2 - 4 K ohms at 150°C(302°F)

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