EGR Temperature Sensor: Testing and Inspection

EGR GAS TEMPERATURE SENSOR INSPECTION
1. REMOVE EGR GAS TEMPERATURE SENSOR.
2. 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 1OO°C (212°F): 11 - 16 k Ohms
- At 150°C (3O2°F): 2 - 4 k Ohms

- If the resistance is not as specified, replace the sensor.

3. REINSTALL EGR GAS TEMPERATURE SENSOR.
