EGR Temperature Sensor: Testing and Inspection

1. Remove the EGR Temperature Sensor.

Testing The EGR Temperature Sensor:

2. Place the sensor in 50~C (122~F) water.

3. Measure the resistance between the terminals.
Refer to SPECIFICATIONS/ELECTRICAL.

4. Increase the water's temperature to 100~C (212~F).
5. Measure the resistance between the terminals.
Refer to SPECIFICATIONS/ELECTRICAL.

If there is a significant deviation from the standard value, replace the EGR Temperature Sensor.
