If the resistance is not as shown in the graph, replace the evaporator temperature sensor.
NOTE:
Inspect the evaporator temperature sensor when it is installed to the A/C unit.
1. Set the fan speed to MAX HI.
2. Set the temperature control to MAX COLD.
3. Set to the RECIRCULATE mode.
4. Turn the A/C switch off.
5. Close all doors and windows.
6. Wait for 5 min.
7. Disconnect the evaporator temperature sensor connector.
8. Measure the temperature at the blower inlet.
9. Measure the resistance between the evaporator temperature sensor terminals.
If the resistance is not as shown in the graph, replace the evaporator temperature sensor.
