COMPONENT TESTING

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 temperature of the water.
   1. At 122°F (50°C), the resistance should be 60–83 kilohms.
   2. At 212°F (100°C), the resistance should be 11–14 kilohms.
3. Replace the EGR temperature sensor if there is a significant deviation from the standard value.
4. Install the EGR temperature sensor and tighten to 7.3–8.6 ft. lbs. (10–12 Nm).
5. Plug all connectors back into their original components.
