EGR Temperature Sensor Circuit:

INSPECTION

1. Remove EGR gas temperature sensor.

2. Inspect EGR gas temperature sensor.

Using an ohmmeter, measure the resistance between the terminals.

Resistance:

69.40 - 88.50 k ohms at 50°C (122°F)

11.89 - 14.37 k ohms at 100°C (212°F)

2.79 - 3.59 k ohms at 150°C (302°F)

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

3. Reinstall EGR gas temperature sensor.
