EGR Temperature Sensor: Testing and Inspection

INSPECTION OF RESISTANCE OF EGR GAS TEMP. SENSOR
(a) Remove the LH engine wire cover.





(b) Using an ohmmeter, measure the resistance between the terminals.

Resistance:
69 - 89 kOhms at 50°C (112°F)
11 - 15 kOhms at 100°C (212°F)
2 - 4 kOhms at 150°C (302°F)

If resistance is not as specified, replace the sensor.

(c) Install the LH engine wire cover.
