Ignition "OFF"
Disconnect evaporator temperature sensor.
Using the multi-tester, Measure resistance between terminal "1" and "2" of evaporator temperature sensor.
Temperature [℃] | Resistance [KΩ] |
-20 | 70.04 |
-10 | 43.35 |
0 | 27.62 |
10 | 18.07 |
20 | 12.11 |
30 | 8.30 |
40 | 5.81 |
50 | 4.15 |
If the measured resistance is not specification, substitute with a known-good evaporator temperature sensor and check for proper operation.
If the problem is corrected, replace the evaporator temperature sensor.
