EGR Temperature Sensor: Testing and Inspection

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

If the resistance is not as specified, replace the sensor.
4. REINSTALL EGR GAS TEMPERATURE SENSOR
5. REINSTALL EGR VALVE
