EGR Temperature Sensor: Testing and Inspection

1. REMOVE EGR VALVE
2. REMOVE EGR GAS TEMPERATURE SENSOR




3. INSPECT EGR GAS TEMPERATURE SENSOR
Using an ohmmeter, measure the resistance between the terminals.

Resistance:
- At 50 °C (122 °F): 64 - 97 kOhms
- At 100 °C (212 °F): 11 - 16 kOhms
- At 150 °C (302 °F): 2 - 4 kOhms

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

4. REINSTALL EGR GAS TEMPERATURE SENSOR
5. REINSTALL EGR VALVE
