EGR Temperature Sensor Location:

1. Remove the EGR temperature sensor from the vehicle.

Fig. 36 Testing The EGR Temperature Sensor:

2. Place the sensor in water.
3. Heat the water to 50 degrees C or 122 degrees F. Verify that the resistance of the sensor falls between 60 and 83k ohms.
4. Heat the water to 100 degrees C or 212 degrees F. Verify the the resistance of the sensor falls between 11 and 14k ohms.
5. When re-installing the temperature sensor tighten it to 10 - 12 Nm or 7.3 - 8.6 ft. lbs.
