Evaporator Temperature Sensor Test
- Remove the evaporator temperature sensor (see EVAPORATOR TEMPERATURE SENSOR REPLACEMENT
).
- Dip the sensor in ice water, and measure the resistance between its terminals.

- Then pour warm water on the sensor, and check for a change in resistance.
- Compare the resistance readings with the specifications shown in the graph; the resistance should be within the specifications.

- If the resistance is not as specified, replace the evaporator temperature sensor (see EVAPORATOR TEMPERATURE SENSOR REPLACEMENT
).
