EGR Temperature Sensor: Testing and Inspection

COMPONENTS

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 k Ohm
- At 100°C (212°F): 11-16 k Ohm
- At 150°C (302°F): 2-4 k Ohm

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

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