How do you find out if your ETOG sensor is defective?

ETOG – Ground Sensor

In order to determine if your sensor is defective, follow the below steps:

1. Disconnect sensor heat (11/12).
2. Wait a few hours to ensure that the sensor is same temperature as the ground.
3. Measure ground/sensor temperature.
4. Disconnect sensor from terminal (13/14) (sensor 2 17/18).
5. Measure sensor resistance (should be 30K ohms at 5 degrees C/41 degrees F, 36276 ohms at 0 degrees C/ 32 degrees F) (purple/gray).
6. If resistance is significantly lower, you sensor is defective. Please continue to work around.
