INSPECTION OF EGR GAS TEMP. SENSOR

INSPECT RESISTANCE OF EGR GAS TEMP. SENSOR

Using an ohmmeter, measure the resistance between the terminals.

Resistance:
69.40 – 88.50 kΩ at 50°C (112°F)
11.89 – 14.37 kΩ at 100°C (212°F)
2.79 – 3.58 kΩ at 150°C (302°F)

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